The reaction 2NO(g) + O2(g) → 2NO2(g) is of the first order If volume of the reaction vessel is reduced to 1/3, the rate of reaction would be


A) 1/3 times

B) 2/3 times

C) 3 times

D) 6 times

Answer:

Option C

Explanation:

For following reaction, 2NO(g) + O2(g) → 2NO2(g)

When the volume of the vessel is reduced to 1/3 then the concentration of the reactant becomes three times. The rate of reaction for the first-order reaction is proportional to the concentration. So the rate of reaction will increase three times.
