Question

Match each decomposition in Column I (total pressure at equilibrium given) with its $K_{p}$ in Column II (a Column I entry may match more than one Column II entry):

Column I (Decomposition)	Column II $(K_{p})$
(P) $N H_{4} H S (s) ⇌ N H_{3} (g) + H_{2} S (g)$ , total 0.6 atm	(1) 0.09
(Q) $N H_{4} Cl (s) ⇌ N H_{3} (g) + H Cl (g)$ , total 2 atm	(2) 0.25
(R) $2 N a H C O_{3} (s)$ ⇌ $N a_{2} C O_{3} (s) + C O_{2} (g) + H_{2} O (g)$ , total 1 atm	(3) 0.5
(S) $A (s) ⇌ 2 B (g) + C (g)$ , total 3 atm	(4) 1
	(5) 4

(P) N H 3 ​ = H 2 ​ S = 0.3 atm : K p ​ = 0.09 (1). (Q) N H 3 ​ = H Cl = 1 atm : K p ​ = 1 (4). (R) C O 2 ​ = H 2 ​ O = 0.5 atm : K p ​ = 0.25 (2). (S) p B ​ : p C ​ = 2 : 1 , so p B ​ = 2 , p C ​ = 1 : K p ​ = 2 2 × 1 = 4 (5). Correct matching: P to 1; Q to 4; R to 2; S to 5. Answer: (B).
