In the following reaction

A \to B + C,

rate constant is

0.001\;\mathrm{M}{\mathrm{s}^{ - 1}}\mathrm{.}

Half-life and completion time of the given reaction are

View answer and explanation

Correct option: A

500 s, 1000 s

Option A (500 s, 1000 s) is correct because for a zero-order reaction, the half-life is a/2k and the completion time is a/k, where a is the initial concentration and k is the rate constant. Assuming initial concentration is 1M, half-life is 500s and completion time is 1000s.
