Question:medium

Calculate the half-life of a first order reaction if the rate constant of the reaction is $2.772 \times 10^{-3}\,\text{s}^{-1}$.

Show Hint

Kinetics Tip: Note that for a first-order reaction, the half-life is constant and does not depend on the initial concentration of the reactant.
