Reaction Rate Constant Calculator

Calculate the rate constant (k) from reaction rate and concentration

About Reaction Rate Constants

The rate constant (k) relates the reaction rate to the concentration of reactants. It depends on temperature and the nature of the reactants but not on concentrations. The units of k vary with reaction order to ensure the rate always has units of M/s.
