Question

The time required for $100\%$ completion of zero order reaction is

• A. $\frac{a}{k}$
• B. $\frac{a}{2k}$
• C. $\frac{2a}{k}$
• D. $\frac{k}{a}$

Answer 1

Answer: (A)

Half-life of a zero order reaction $=\frac{a}{2k}$

Time taken for completion $=2t_{1/2}=2\times \frac{a}{2k}$

$=\frac{a}{k}$
