The purpose of this experiment is to determine the effect of changing the concentration of a reactant upon the rate of a reaction. In order to understand the effect of concentration on rate, we must recall the three critical things that must happen if a chemical reaction is to occur. These are: * Molecules must collide * Collisions must bring the reactive sites together * Collisions must have sufficient energy to break and remake bonds Concentration effects the number of molecular collisions that occur in any given period of time. To understand this we can consider a simple container filled with a gas. Selecting some point in the container, we ask what is the probability of a molecule being at this point at any time. What is a reaction? A reaction is when two particles (reactants) join to form a new product or products. What is rate? Rate is a measure...
