A) 1 h
B) 0.5 h
C) 0.25 h
D) 2h
Correct Answer: A
Solution :
In case I, fraction of A reacted \[=\frac{0.6}{0.8}=\frac{3}{4}\] In case II, fraction of A reacted \[=\frac{0.675}{0.9}=\frac{3}{4}\] For a first order reaction, time taken for the same fraction of reaction is independent of initial concentration.You need to login to perform this action.
