Match each reaction in Column I with the value of K P / K C in Column II (a Column I entry may match more than one Column II entry): Column I (Reaction) Column II ( K P / K C ) (P) N 2 ( g )

Question

Match each reaction in Column I with the value of $K_{P} / K_{C}$ in Column II (a Column I entry may match more than one Column II entry):

Column I (Reaction)	Column II $(K_{P} / K_{C})$
(P) $N_{2} (g) + O_{2} (g) ⇌ 2 NO (g)$	(1) $(RT)^{- 1}$
(Q) $2 S O_{2} (g) + O_{2} (g) ⇌ 2 S O_{3} (g)$	(2) $(RT)^{0}$
(R) $C (s) + ½ O_{2} (g) ⇌ CO (g)$	(3) RT
(S) $PC l_{5} (g) ⇌ PC l_{3} (g) + C l_{2} (g)$	(4) $RT$

K P ​ / K C ​ = ( RT ) Δ n (gaseous species only). (P) Δ n = 0 : ( RT ) 0 (2). (Q) Δ n = 2 − 3 = − 1 : ( RT ) − 1 (1). (R) C is a solid: Δ n = 1 − 0.5 = + 0.5 : RT ​ (4). (S) Δ n = 2 − 1 = + 1 : RT (3). Correct matching: P to 2; Q to 1; R to 4; S to 3. Answer: (B).
