Question

The rate constant of a reaction is equal to the rate of reaction when the concentration of each ______ is ______.

Answer 1

The rate constant of a reaction is equal to the rate of reaction when the concentration of each reactant is unity.

Explanation:

The rate constant (k) is defined from the rate law:

Rate = k[A]^m[B]ⁿ....

If the concentration of each reactant is taken as unity (1 mol L⁻¹), then:

Rate = k × 1 m × 1 n = k
