Question

A first order reaction is found to have a rate constant,k=7.9×10^-20 s^-1. Find the half life of the reaction

Answer 1

Explanation:

A first order reaction is found to have a rate constant, K=7.9×10^−14 S^−1. 

The relationship between the half life period (t1/2) and the rate constant, K for first order reaction is given by the following expression.

t1/2=0.693/K

Substitute values in the above expression.

t1/2= 0.693/7.9×10^−14 S^−1.

(do the calculations, I have given u the main expression)
