Q4Multiple choice
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 3 –1
- (i)1.8 × 10 mol L –3
- (ii)1.8 × 10 –3 –1
- (iii)1.8 × 10 L mol
- (iv)0.55 × 10
Show answer
(ii) 1.8 × 10 –3 –1
