The rate of a chemical reaction is the speed at which a chemical reaction proceeds. It is usually expressed as the change in concentration of reactants/products over time.

For a chemical reaction:

A → B

Rate = k[A]

k is the rate constant. It is a proportionality constant in the rate expression that links the rate of reaction to the concentrations of reactants.
