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

Options

A. introducing chlorine gas at constant volume
B. introducing an inert gas at constant pressure
C. increasing the volume of the container
D. introducing `PCl_(5)` at constant volume

Answer

A

Explanation

According to `K_(p)=P_(PCl_(3)(g)xxP_(Cl_(2)(g)))/(P_(PCl_(5)(g)))=((n_(PCl_(3)(g)))_(eq.)xx(n_(Cl_(2)(g)))_(eq.))/(Vxx(n_(PCl_(5)(g)))_(eg.))`
and on adding inert gas at constant pressure effect on equilibrium will be similar to as if volume of container has been increased.
