For the reaction PCl(5(g))hArrPCl(3(g))+...

For the reaction `PCl_(5(g))hArrPCl_(3(g))+Cl_(2(g))`, the forward reaction at constant temperature is favoured by

A

Introducing an inert gas at constant volume.

B

Introducing chlorine gas at constant volume,

C

Introducing an inert gas at constant pressure

D

Increasing the volume of the container.

Text Solution

Verified by Experts

The correct Answer is:
C, D
At constant volume, There is no effect of addition of inert gas to a reaction in equilibrium. At constant pressure, for the reactions for which `Deltan=0`. There is no effect of addition of inert gas to a reaction in equilibrium. At constant pressure, for the reaction for which `Deltan ne 0`, the equilibrium shifts in the direction of more number of moles. Addition of the reactant favours forward reaction. Increasing the volume means decreasing the pressure, which shifts the reaction in the direction of more number of gaseous moles.
