The time required for \(100 \%\) completion of a zero order reaction is
- A \(a k\)
- B \(\frac{a}{2 k}\)
- C \(\frac{a}{k}\)
- D \(\frac{2 k}{a}\)
Answer & Solution
Correct Answer
(C) \(\frac{a}{k}\)
Step-by-step Solution
Detailed explanation
Half-life of a zero order reaction \(=\frac{a}{2 k}\)
Time taken for completion \(=2 t_{1 / 2}=2 \times \frac{a}{2 k}\)
\[
=\frac{a}{k}
\]
Time taken for completion \(=2 t_{1 / 2}=2 \times \frac{a}{2 k}\)
\[
=\frac{a}{k}
\]
