In which of the following reaction Kp Kc ?

Question

In which of the following reaction Kp > Kc ? (A) PCl3 + Cl2 → PCl5 (B) H2 + I2 → 2HI (C) 2SO3 → O2 + 2 SO2 (D) N2 + 3H2 → 2NH3

Kp = Kc (RT)Δ n Δ n = change in number of moles If Δn = positive then Kp will be greater than Kc. PCl3 + Cl2 → PCl5, Δ n = 1-2 = -1; Kp < Kc H2 + I2 → 2HI, Δ n = 0 ; Kp = Kc 2SO3 → O2 + 2SO2 , Δ n = 1; Kp > Kc N2 + 3H2 → 2NH3 ; Δ n = -2; Kp < Kc

Q. In which of the following reaction $K_{p} > K_{c}$ ?

$PC l_{3} + C l_{2} \to PC l_{5}$

$H_{2} + I_{2} \to 2 H I$

$2 S O_{3} \to O_{2} + 2 S O_{2}$

$N_{2} + 3 H_{2} \to 2 N H_{3}$
