The Rate Law calculator has rate of reaction functions for Zero Order, First Order and Second Order reactions as follows:

#### The Science

Kinetics is a category in chemistry concerned with the rate of the reaction. The rates of reactions are dependent on temperature, concentration of reactants, presence of catalysts and molecular mechanisms by which the reaction occurs. The rate of the reaction is proportional to the concentration of the reactants or products, and depending on the order of the reaction, is raised to the power of that order. On molecular level reactions occur either unimolecularly or bimolecularly, where the structure of the reactant(s) changes due to collisions. In order for the molecular structure change to occur, an amount of energy called activation energy must be given for the reaction to occur.
