Question 53

Phosphorus pentachloride gas decomposes reversibly. The forward reaction is endothermic.

PCl5(g)⇌PCl3(g)+Cl2(g)\text{PCl}_5(\text{g}) \rightleftharpoons \text{PCl}_3(\text{g}) + \text{Cl}_2(\text{g})PCl5​(g)⇌PCl3​(g)+Cl2​(g)

Explain the effect of decreasing the temperature on the equilibrium yield of chlorine.
