Solution 1

When the concentration (active mass) of each reactant is at unity, the rate constant of a chemical reaction equals the rate of the reaction.

∵ Rate of reaction ∝ [Reactant]

If A → product, then

rate (R) = k[A]

If [A] = 1, then rate, R = k,

where k is the rate constant.

Solution 2

  1. The rate constant of a reaction is equal to the rate of reaction when the concentration of each of the reactants is unity.
  2. At a specific temperature, a reaction's rate constant has a fixed value. As the temperature rises, so does its worth. It is independent of the reactant concentrations at the initiation.
