What is the time required for \(99 \%\) completion of a first order reaction if rate constant is \(23.03 \mathrm{~min}^{-1}\) ?
- A 0.2 minute
- B 0.4 minute
- C 6.2 minute
- D 8.1 minute
Answer & Solution
Correct Answer
(A) 0.2 minute
Step-by-step Solution
Detailed explanation
\( t = \frac{2.303}{k} \log \left( \frac{[A]_0}{[A]} \right) \) \( t = \frac{2.303}{23.03 \mathrm{~min}^{-1}} \log \left( \frac{1}{1-0.99} \right) \)
