Rate of Reaction Introduction: The RATE of a reaction is the SPEED at which a reaction happens. If a reaction has a low rate that means the molecules combine at a slower speed than a reaction with a high rate. Some reactions take hundreds, maybe even thousands of years while other can happen in less than one second. The rate of reaction depends on the type of molecules, which are combining. There is another big idea with rates of reaction... COLLISION THEORY. The collision theory says that the more collisions in a system, the more likely combinations of molecules will happen. So if there are a higher number of collisions in a system... More combinations of molecules will occur, the reaction will go faster, and the rate of that reaction will be higher. Forces that change the speed of reactions: Reactions happen, no matter what. Chemicals are always combining or breaking down....
