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.
