In which of the following equilibrium, K and K are not equal? (a) 2NO

1.	In which of the following equilibrium, K and K are not equal? (a) 2NO(g) ⇌ N2(g) + O2(g) (b) SO2(g) + ⇌ NO2(g) SO3(g) + NO(g) (c) H2(g) + I(g) ⇌ 2HI(g) (d) PCI5 (g) ⇌ PCl3(g) + Cl2(g)
Answer» (d) PCI₅ ⇌ (g) PCl_3(g) + Cl_2(g) For reactions given in options (a), (b) and (c) ∆n_g = 0 For option (d) ∆n_g = 2 – 1 = 1 ∴ K_p = K_c (RT)

In which of the following equilibrium, K and K are not equal? (a) 2NO(g) ⇌ N2(g) + O2(g) (b) SO2(g) + ⇌ NO2(g) SO3(g) + NO(g) (c) H2(g) + I(g) ⇌ 2HI(g) (d) PCI5 (g) ⇌ PCl3(g) + Cl2(g)

Answer»

(d) PCI₅ ⇌ (g) PCl_3(g) + Cl_2(g)

For reactions given in options (a), (b) and (c) ∆n_g = 0

For option (d) ∆n_g = 2 – 1 = 1

∴ K_p = K_c (RT)
