Chemical kinetics describes the mechanisms of chemical reactions and the rates associated with them.
The reaction rate is affected by the concentration of the reactants, the temperature of the reaction, the pressure at which the reaction is taking place, and the state of matter of the reactants.
The reaction rate describes the change in concentration of the product with time. The reaction rate is defined in units of M/s.
The reaction order describes the dependence of the reaction rate on the concentration of each reactant. It is not related to stoichiometry.
The reaction rate constant varies depending on the reaction, but it is influenced by reaction temperature. The units of the reaction rate constant depend on the order of the reaction. The units of rate constant are M/s for zero-order reactions, 1/s for first-order reactions, and 1/M⋅s for second-order reactions.
