PCl 5 , PCl 3 and Cl 2 are at Equilibrium at 500K in a closed container and their concentrations are 0.8 × 10 -3 mol L -1 , 1.2 × 10 -3 mol L -1 and 1.2 × 10 -3 mol L -1 respectively. The value of K c for the reaction PCl 5 (g) ⇋ PCl 3 (g) + Cl 2 (g) will be

Question

Philoid · Accepted Answer

• For the reaction PCl₅ (g) ⇋ PCl₃ (g) + Cl₂

The reaction Equilibrium constant K_c can be written as :

Hence, =

K_c = 1.8 × 10^-3

PCl5, PCl3 and Cl2 are at Equilibrium at 500K in a closed container and their concentrations are 0.8 × 10-3 mol L-1, 1.2 × 10-3 mol L-1 and 1.2 × 10-3 mol L-1 respectively. The value of Kc for the reaction PCl5 (g) ⇋ PCl3 (g) + Cl2 (g) will be

PCl₅, PCl₃ and Cl₂ are at Equilibrium at 500K in a closed container and their concentrations are 0.8 × 10^-3 mol L^-1, 1.2 × 10^-3 mol L^-1 and 1.2 × 10^-3 mol L^-1 respectively. The value of K_c for the reaction PCl₅ (g) ⇋ PCl₃ (g) + Cl₂ (g) will be
