The reactions PCl 5 (g) 
PCl 3 (g) + Cl 2 (g) and COCl 2 (g) 
CO(g) + Cl 2 (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
Text Solution
Verified by ExpertsThe correct answer is:
C
Addition 
shifts reaction (ii) in the backward direction. This in turn decreases 
which causes relation (i) to shift in forward direction and therefore concentration of 
will decrease.
