Question

In which of the following reaction Kp = Kc ? (A) PCl3+Cl2→ PCl5 (B) H2+I2→2HI (C) H 2( g )+ Cl 2( g ) leftharpoons 2 HCl ( g ) (D) N2+3H2→2NH3

Tardigrade Admin · Accepted Answer

K p = K c ( RT ) Δ n If Δ n =0, K p = K c If Δ n >0, then K p > K c If Δ n <0, then K p < K c For the reaction: H 2( g )+ Cl 2( g ) leftharpoons 2 HCl ( g ) Δ n is the number of moles of gaseous products - number of moles of gaseous reactants in a balanced equation. beginarrayl Δ n =2-(1+1)=0 ∴ K p = K c endarray

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

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

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

$H_{2 (g)} + C l_{2 (g)} ⇌ 2 H C l_{(g)}$

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