Question

Match list - I (equilibrium) with list - II (conditions favouring the products) and select the correct code

List - I (Equilibrium)	List - II (Conditions)
(P) $C (s) + C O_{2} (g) ⇌ 2 CO (g)$ Endothermic	(1) High temperature
(Q) $N_{2} (g) + 3 H_{2} (g) ⇌ 2 N H_{3} (g)$ Exothermic	(2) Low temperature
(R) $H_{2} (g) + I_{2} (g) ⇌ 2 H I (g)$ Exothermic	(3) High pressure
	(4) Low pressure
	(5) Independent of pressure

(P) Endothermic, Δ n = 2 − 1 = + 1 : high temperature (1), low pressure (4). (Q) Exothermic, Δ n = − 2 : low temperature (2), high pressure (3). (R) Exothermic, Δ n = 0 : low temperature (2), pressure has no effect (5). Correct matching: P to 1,4; Q to 2,3; R to 2,5. Answer: (D).
