Get A Reaction Out Of This! A chemical reaction occurs when one or more substances change to produce one or more different substances. For example, some evidence that a chemical reaction has occurred is possible changes in energy, release of energy, formation of a new substance, or reduction or increase in temperature. This lab will be conducted in order to create a chemical reaction by changing the reaction rate of a substance. In order to change the reaction rate, a catalyst needs to be added.in this case the catalyst in a hydrogen ion. Iodine and propane will be mixed and then catalyzed by the hydrogen ions, in turn helping to change the rate of the reaction. Some terms and ideas that will explored in this experiment are the rate of a chemical reaction and seeing how it is affected by the concentration of the reactant or reactants. Reactant concentration is the strength of the solution. The way reactants concentration affects the reaction rate is commonly known as the rate law. "The rate law can only be experimentally determined and can be used to predict the relationship between the rate of a reaction and the concentrations of reactants,"(Holt 2006). To understand or determine the rate of this chemical process one can make an educated guess about the reaction mechanism. "The reaction mechanism is the way in which a chemical reaction takes place, expressed in a series of chemical equations. A reaction that involves a single reactant, the rate is often proportional to the concentration of the reactant raised to some power” (Holt 2006). Rate= k [reactant]n is the formula used when determining rate law. The order of the reaction is represented by the exponent n. Based off the of the number of molecules that enter the... ... middle of paper ... ...ach of these elements are used in the real world. For example, propane is used to fuel grills and hot air balloons; it is also used to power airsoft/paintball guns, and also used in movie sets to cause explosions. But most importantly, propane heats many households throughout the United States, keeping people warm in the coldest of times. Iodine, on the other hand, is most commonly used as an antiseptic to treat minor cuts and abrasions. Iodine can also be found in some household cleaning products and can also be found in food: seafood, dairy, and canned soups. <---- we need to cite where we got this info As mentioned before, there are no relationships between these two elements, but the elements can be found everywhere in everyday life. So, next time an individual heats up the barbecue, or opens a can of soup, think about the reaction occurring with each element.
