A) \[4.6\times {{10}^{-2}}s\]
B) \[4.6\times {{10}^{4}}s\]
C) \[4.6\times {{10}^{2}}s\]
D) \[4.6\times {{10}^{-4}}s\]
Correct Answer: A
Solution :
\[t=\frac{2.303}{k}\log \frac{{{[A]}_{0}}}{[A]}\] \[=\frac{2.303}{60}=\log \frac{a}{\frac{a}{16}}=\frac{2.303}{60}\log 16\] \[=\frac{2.303}{60}\times 1.204\] \[=0.0462s=4.6\times {{10}^{-2}}s\]You need to login to perform this action.
