Question

Define half life reaction. Show that for a first order reaction half is independent of initial concentration

Answer 1

Explanation:

Half-life period of a first order reaction. Since k is a constant for a given reaction at a given temperature and the expression lacks any concentration term so from equation 3 it is evident that half-time of a 1st order reaction is a constant independent of initial concentration of reactant.

Answer 2

The time at which the concentration of reactants become half of its original or initial concentration is called as half life time of the recation.
