A) \[2\min \]
B) \[4\min \]
C) \[12\min \]
D) \[1\min \]
Correct Answer: B
Solution :
First order kinetic equation is: \[k=\frac{2.303}{t}\log \frac{a}{(a-x)}\] or \[t=\frac{2.303}{k}\log \frac{a}{(a-x)}\] According to question \[8=\frac{2.303}{k}\log \frac{100}{100-75}\]You need to login to perform this action.
