1 answers

Dr. Kamlapati Bhatt 8 years, 3 months ago

In chemical kinetics the value of rate constant ,k, quantifies the rate of a chemical reaction.

Rate constant is defined as the rate of a reaction when concentration of each reactant is taken as unity.

Some important charecteristics of a rate constant are ,

1. It is a measure of rate of a reaction . Greater the value of rate constant faster is the rate of reaction

2. Each reaction has definite value of rate constant at a fixed temperature.

3. The value of rate constant for the same reaction changes with temperature

4. The unit of rate constant depends upon order of reaction..
