A first order reaction is \(50 \%\) completed in 16 minute. Find the percentage of reactant reacting in 32 minute.
- A \(25 \%\)
- B \(40 \%\)
- C \(50 \%\)
- D \(75 \%\)
Answer & Solution
Correct Answer
(D) \(75 \%\)
Step-by-step Solution
Detailed explanation
\( n = \frac{32 \text{ minute}}{16 \text{ minute}} = 2 \) \( \text{Percentage remaining} = (0.5)^n \times 100\% = (0.5)^2 \times 100\% = 25\% \)
