Chemical Kinetics Question 73
Question: The reaction $ 2NO(g)+O_2(g) $ ⇌ $ 2NO_2(g) $ is of first order. If volume of reaction vessel is reduced to 1/3, the rate of reaction would be [MP PMT 2001]
Options:
A) 1/3 times
B) 2/3 times
C) 3 times
D) 6 times
Show Answer
Answer:
Correct Answer: C
Solution:
For following reaction, $ 2N{O_{(g)}}+O_2(g)\to 2NO_2(g) $
When the volume of vessel change into $ \frac{1}{3} $ then concentration of reactant become three times.
The rate of reaction for first order reaction $ \propto $ concentration. So rate of reaction will increases three times.
