For the equilibrium, PCl5 $⇌$ PCl3 + Cl2,

${\mathrm{K}}_{\mathrm{C}}={\mathrm{\alpha }}^{2}/\left(1-\mathrm{\alpha }\right)\mathrm{V}$, temperature remaining constant:

1. Kc will increase with the increase in volume

2. Kc will increase with the decrease in volume

3. Kc will not change with the change in volume

4. Kc may increase or decrease with the  change in volume depending upon its numerical value.
