A) \[\text{0}\text{.384 min}\]
B) \[\text{0}\text{.15}\,\text{min}\]
C) 3 min
D) \[\text{3}\text{.84}\,\text{min}\]
Correct Answer: A
Solution :
We know that for first order kinetics \[K=\frac{2.303}{t}\log \frac{a}{a-x}\] Here\[K=6{{\min }^{-1}},a=0.5\,mol\,{{L}^{-1}}\] \[(a-x)=0.05mol\,{{L}^{-1}}\] \[6=\frac{2.303}{t}\log \frac{0.5}{0.05}\] or \[t=\frac{2.303}{6}\log \frac{0.5}{0.05}=\frac{2.303}{6}=0.384\]You need to login to perform this action.
