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 |
\[k=\frac{2.303}{t}\log \frac{a}{a-x},\left( a-x \right)=0.05mol\text{ }{{l}^{-1}}\] |
\[6=\frac{2.3030}{t}\log \frac{0.5}{0.05}\] |
or \[t=\frac{2.303}{6}\log \frac{0.5}{0.05}=\frac{2.303}{6}=0.384\text{ }\min \] |
