हिन्दीWhen initial concentration of the reactant is doubled, the half-life period of a zero order reaction _______.
View Answer & Solution
Correct answer · Option B
is doubled
Explanation
For a zero-order reaction, half-life \( t_{1/2} = \frac{[A]_0}{2k} \). Thus, \( t_{1/2} \) is directly proportional to initial concentration \( [A]_0 \), so doubling it doubles the half-life.
