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.
