... Rate is a measure of speed of any change that occurs within an interval of time In chemistry, the reaction rate (rate of a chemical change) = amount of reactant per unit time o For example: 0.2 mol/1 month Collision theory- atoms, molecules, and ions can react to form products when they collide with ...
