Chemical Kinetics Question 170
In the reaction $ A\to B+C $ , rate constant is $ 0.001M{s^{-1}} $ . If we start with 1 M of A then concentration of A and B after 10 minutes are respectively.
Options:
A) 0.5 M, 0.5 M
B) 0.6 M, 0.4 M
C) 0.4 M, 0.6 M
D) 0.6 M 0.5 M
Show Answer
Answer:
Correct Answer: C
Solution:
$ {{[A]}_{t}}=[A]e^{-kt}=1\times e^{-0.001\times 10\times 60} $
$ =0.4M $
$ {{[B]}_{t}}=0.001\times 10\times 60=0.6M $
