Aims and Objectives
Introduction: In this coursework, I will be conducting an experiment,
to show a particular factor affects the rates of a chemical reaction.
The main factors include concentration/pressure of the reactants,
presence of catalysts, particle size and temperature. I have chosen
the effect of temperature on a chemical rate of reaction.
Aims: The aim of this investigation is to find out the effect of
Temperature of the acid, in the reaction between dilute hydrochloric
acid and magnesium ribbon. This reaction is a single displacement
reaction, which is when one of the atoms' formulas is exchanged with
another one's, like A + BC è AC + B
The rate of a chemical reaction is a measure of how fast the reaction
takes place. It is important to remember that a rapid reaction is
completed in a short period of time. The following is the equation for
this reaction that I will use for this experiment:
2Mg + 2HCl =====è 2MgCl + CO2
I also hope to find a certain pattern; by devising formulas from my
results I can compare different temperatures and their rates of
reaction among each other, which should suit my prediction.
Skill Area P :Planning Experimental Procedures
Plan: For this coursework I plan to conduct a suitable experiment to
show how different temperatures affect the rate of a chemical
reaction, from this I hope to aim for precise and reliable results.
The following reaction is what will happen in my experiment:
2Mg + 2HCl =====è 2MgCl + CO2
Safety Precautions: In the experiment we will ensure that the
following safety precautions are taken:
· Safety goggles must be worn at all times during the experiment.
· We will need to be aware of your surroundings. When handling
chemicals such as hydrochloric acid should be handled with care.
Spillages, breakages, of any kind are a danger hazard, must be
supervised and reported.
· We will need to rid your hands of any traces of chemicals such as
Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature-
I am going to investigate how the concentration of hydrochloric acid alters the rate of reaction. As I increase the amount of water, I
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
Hydrochloric acid + calcium carbonate arrow calcium chloride + carbon dioxide + water. HCl(aq) + CaCO3(s) arrow CaCl2(aq) + CO2(g) + H2O(l) Things that affect the reaction rate of this experiment are: 1. The temperature of the hydrochloric acid. 2.
Rate of Reaction Between Marble Chips and Hydrochloric Acid. The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) is used. There are many variables that affect the rate of this reaction such as the following. 1.
The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
In a substance the rate of reaction will be quicker if it has a large
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
reaction is the rate of loss of a reactant or the rate of formation of
The aim of this experiment was to investigate the affect of the use of a catalyst and temperature on the rate of reaction while keeping all the other factors that affect the reaction rate constant.
My aim in this piece of work is to see the effect of temperature on the rate of a reaction in a solution of hydrochloric acid containing sodium thiosulphate.
The aim of my investigation is to find out whether the increase of temperature increases the rate of reaction between the two reactants of Sodium Thiosulphate and Hydrochloric acid. I will then find out and evaluate on how temperature affects this particular reaction. Factors There are four main factors, which affect the rate of reaction that are considered as variables for the experiment I will be doing, they are the following: Molecules can only collide when two of them meet together.
The pH of the solution would alter the rate of the reaction if it was
• Washing hands after touching blood, body fluids, or other contaminated items, even when gloves are worn.
The purpose of this investigation is to investigate how one variable (temperature in this experiment) will affect the rate of a chemical reaction. The rate of any chemical reaction always depends on the reactant concentrations, surface area of reactants and the temperature.
