Difference Between Rate Constant and Specific Rate Constant

The major difference between Rate Constant and Specific Rate Constant is that Rate Constant is a constant of proportionality in the rate Law Equation and is equal to the rate of reaction when the molar concentration of each reactant is unity while Specific Rate Constant ( Rate of Reaction) is the change in concentration of the reactant or product per unit time.

Difference Between Rate Constant and Specific Rate Constant

Rate Constant

  1. It is proportionality constant in the rate expression.
  2. It is the ratio between the rate of reaction and the concentration of reactants.

Specific Rate Constant

  1. It is the rate of reaction when the molar concentration of each reactant is unity, i.e. 1 mol / dm3.
  2. It is equal to the rate of a reaction.
