Q. Rate constant for a reaction is $\lambda.$ Average life is represent by
A) $\frac{1}{\lambda}$
B) $\frac{1n^{2}}{\lambda}$
C) $\frac{\lambda}{\sqrt{}2}$
D) $\frac{0.693}{\lambda}$
Explanation
(a)
Average life is defined as, “reciprocal of decay constant.” If decay constant for a reaction is $\lambda$ then,
Average life=$\frac{1}{\lambda}$
