Question

Half life period of first order reaction in 10 minutes calculate the rate constant of the reaction

Answer 1

Half life and rate constant for a first order reaction are related by,

$t_{\frac{1}{2} } =\frac{0.693}{k}\\ k =\frac{0.693}{10 min} \\ = 0.0693 min^{-1}$

Rate constant of the reaction is 0.0693 min^-1
