Experiment 1: Introducing Equilibrium I (Appendix 1) The purpose of this experiment was to observe what happens when the reactants and productions of a reversible reaction are placed separately into a sealed container. This experiment investigated the chemistry of equilibrium using N_2 O_4 ⇋ 〖2NO〗_2. This experiment will determine if dynamic chemical equilibrium can be achieved by starting with either reactants or products. In part one of the experiment, the following conditions were: Volume
Solubility Equilibrium is an equilibrium constant for a solid dissolving in an aqueous solution. When there is a solid before the equilibrium sign and dissolved products after the equilibrium sign, it is talking about the solubility product. Also, referred to as Ksp. To solve Ksp you need the concentration of the two dissolved products. The equation of Ksp is... aA(s)⇌cC(aq)+dD(aq)
reaction. The desired product accumulates only if the equilibrium constant is favorable. As it happens, the equilibrium constant for this reaction is rather small (~4) (comparing bond energies in the reactants and products will tip you off as to why the equilibrium constant is so small). Therefore, simply mixing equal amounts of the starting materials will convert only about 67% of the starting material into product. To drive the equilibrium forward Le Chatelier's principle is used, in this case
the outstanding work of Henry Louis Le Chatelier. Le Chatelier studied chemistry extensively in school and made great discoveries as a teacher of the science at colleges in France. He is most known for the principle named after him: Le Chatelier’s Principle, which I will go into detail with later in the paper. My goal in this paper is to bring to light the significance of Le Chatelier’s life and his work in the field of chemistry and science. To achieve this goal I have organized my paper into four
be broken down into smaller controlling factors. The global energy balance is an equal balance of short-wave radiation coming into the atmosphere and long-wave radiation going out of the atmosphere. This is called thermal equilibrium. The earth is at thermal equilibrium; however, there can have a surplus or deficit of energy in parts of the heat budget. If you have a net radiation surplus warm air will rise, and a net radiation deficit will make the air cool an fall. Air gets heated at the
that if a change is made to a system in equilibrium, the system reacts in such a way as to tend to oppose the change, and a new equilibrium is formed. For example, whatever is done to the equilibrium, the system does the opposite. If something is added to a system at equilibrium, the system will behave as to remove it and vice versa. By increasing the concentration of a reaction, it will result in an increase of the rate of reaction. The new equilibrium will have a higher concentration of products
Consumer Equilibrium and the Law of Equi-Marginal Utility Introduction The Law of Equi-Marginal Utility is an extension to the law of diminishing marginal utility. The principle of equi-marginal utility explains the behavior of a consumer in distributing his limited income among various goods and services. This law states that how a consumer allocates his money income between various goods so as to obtain maximum satisfaction. Assumptions The principle of equi-marginal utility is based on the
In the review article, “Equilibrium Theory of Island Biogeography and Ecology”, Simberloff (1974) described how the equilibrium hypothesis can be used to explain island biogeography. According to the author, islands offer significant scientific, economic, evolutionary, or ecologic importances due to their unique characteristics (isolation, insular depauperization). However, detailed study on the somewhat puzzling island biogeography is limited. Therefore, Simberloff (1974) provided an in-depth research
detached from the mass. The dots marked on the tape were examined. During the oscillation, the pendulum bob accelerated and then decelerated when it was approaching its highest position. The acceleration of the bob was always pointing towards its equilibrium position. 3. The two most widely spaced dots were marked on the tape - the zero position of the pendulum bob was found. 4. Every dot on the tape was marked from the zero position. The displacements of these points from the zero position
Investigate the Osmotic Point of Equilibrium in a Potato The following Passages are information which I have managed to find when researching the topic of Osmosis: - The cell membrane controls the movement of substances going into and out of the cells. The cell therefore controls the Chemical composition of the internal environment of the cell. It does this in two ways; Passive Process - this does not require energy Active Process - this does require energy to occur This works in principle which
Addition of Torques Objective: To ascertain equilibrium of the meter stick. Doing so by finding missing variables consisting of torque, length, weight and mass. Record all results and compare to calculated results. Procedure: (Lab part A) • A fiberglass meter stick is to be used. Suspend this meter stick using string. • Hang 100 gram weight from the meter stick with a string a the 10 cm point on the meter stick. • Move the loop that suspends the meter stick left or right
Landforms and Processes All rivers aim to reach equilibrium so they are balanced and when they are in equilibrium from source to mouth a smooth curve is created called the graded long profile. However, as you can see from the diagram many rivers such as The Afon Glaslyn, do not acheive equilibrium and reach their graded long profile: Long Profile of Afon Glaslyn River with graded long profile [IMAGE][IMAGE] Rivers become out of equilibrium when there is a change in base (sea) level. There
Making Moral Decisions: The Synergistic-Reflective-Equilibrium Model ABSTRACT: This treatise is a contribution towards the understanding of why humankind cannot agree on the foundation of morality and why moral pluralism is the logical constitution of moral reality. The synergistic-reflective-equilibrium model is the model that will describe how persons can make moral decisions as pluralistic agents. If this model is correct, then it will not be a new discovery, rather, it will be a new description
offspring have the same genotype ratio as their parents. This example was one of Hardy-Weinberg equilibrium. The next generation will express the same genotype ratio as their parents, and so on. But what exactly is needed to create Hardy-Weinberg equilibrium? (Basically, a population in Hardy-Weinberg equilibrium s not evolving in any way.) Five specific factors are needed to create Hardy-Weinberg equilibrium within a population- a very large population, isolation from other populations, no net mutations
Freight Market Equilibrium Theory An amazing assortment of goods are moved over the worlds ocean trade routes. Of necessity, the carriers charge for the service they render. These charges vary almost as widely as do the cargoes, for they mirror both the shipowner’s costs and the special conditions prevailing on the trade routes traversed by the ships. Ocean freight rates may be described as the prices charged for the services of water carriers. Each ship operator develops it’s own rates, usually
Vertigo and Its Treatment In our everyday lives, we almost take for granted this idea of balance or equilibrium that is maintained within our bodies. In general, no real thought processes are required. It is only when something is disturbed within our balance system that one is able to take notice of changes in the equilibrium. There may be several different factors that cause a disturbance to our bodies. One major area pertains to dizziness. Dizziness is found to be "the chief complaint in
metaphysics, axiology, epistemology, praxis, and aesthetics. The sacred force gave them the wisdom to make choices that help them maintain the proper path. The world is filled with pain, sorrow, and suffering, but wisdom can teach you how to maintain equilibrium and reduce misfortune. This was not wisdom in the modern sense, but rather it was wisdom in making choices that kept you along the right path while walking the slippery slope of the world. The Nauha conception of balance carries also into their

Justification by Reflective Equilibrium Famously, John Rawls is regarded as using reflective equilibrium (RE) to justify his principles of justice. But the point of justification by RE in Rawls's more recent work is not easily established since he regards his own work as still contractarian. In order to clarify matters, I distinguish between wide and narrow RE, as well as show that wide RE consists of several kinds of narrow RE: RE as a plea for (re)consideration, RE as a constructive procedure
