# NEET Chemistry Chemical Kinetics Questions Solved

BOARD

Explain the following terms:

(i) Rate constant (k)

(ii) Half life period of a reaction (${t}_{1}{2}}$)

(i) Rate constant (k) : It is a proportionality constant and is equal to the rate of reaction when the molar concentration of each of the reactants is unity.

(ii) Half life period of a reaction (${t}_{1}{2}}$) : The time taken for half of the reaction to complete is called half life period.
