Question

The reactions PCl5(g) ⇋  PCl3(g) + Cl2(g) and COCl2(g) ⇋ CO(g) + Cl2(g) are simultaneously in equilibrium at constant volume. A few moles of CO(g) are introduced into the vessel. After some time, the new equilibrium concentration of

Options

A.PCl5 will remain unchanged
B.Cl2 will be greater
C.PCl5 will become less
D.PCl5 will become greater

Solution

Cl2 (g) will get consumed and PCl5 will furnish Cl2 in the first reaction.
