Question

The reaction 2NO(g) + O2 (g) leftharpoons 2NO2 (g) is of first order. If volume of 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

Tardigrade Admin · Accepted Answer

2NO (g) + O2 (g) longrightarrow 2NO2 (g) When the volume of vessel change into (1/3) then concentration of reactant become three times. The rate of reaction for first order reaction is directly proportional to concentration. Therefore, rate of reaction will increase three times.

Q. The reaction $2 NO (g) + O_{2} (g) ⇌ 2 N O_{2} (g)$ is of first order. If volume of reaction vessel is reduced to $\frac{1}{3},$ the rate of reaction would be

$\frac{1}{3}$ times

$\frac{2}{3}$ times

3 times

6 times

$2 NO (g) + O_{2} (g) ⟶ 2 N O_{2} (g)$
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 is directly proportional to concentration. Therefore, rate of reaction will increase three times.

Q. The reaction 2NO(g)+O2​(g)⇌2NO2​(g) is of first order. If volume of reaction vessel is reduced to 31​, the rate of reaction would be

31​ times
