Question

First order reaction is found to have rate constant is equals to 5.5 into 10 to the power minus 14 per second find the half-life of the reaction

Answer 1

The half-life of a reaction is the time required for the reactant concentration to decrease to one-half its initial value. The half-life of a first-order reaction is a constant that is related to the rate constant for the reaction: t1/2 = 0.693/k.
