A) 0.384 min
B) 0.15 min
C) 3 min
D) 3.84 min
Correct Answer: A
Solution :
We know that for first order kinetics \[k=\frac{2.303}{t}\log \frac{a}{a-x}\] \[(a-x)=0.05\,\,mol\,\,{{l}^{-1}}\],\[6=\frac{2.303}{t}\log \frac{0.5}{0.05}\] or \[t=\frac{2.303}{6}\log \frac{0.5}{0.05}=\frac{2.303}{6}=0.384\,\min \]You need to login to perform this action.
