Question

PCl5, PCl3 and Cl2 are at equilibrium at 500 K in a closed container and

their concentrations are 0.8 x 10-3 molL-1

, 1.2 x 10-3 mol L 1and1.2 x 10-3 mol L-1

If decomposition is depicted as PCl5(g) ⇌PCl3(g) + Cl2(g) H

0 =124.0kJ/mol

What will be the value of Kc for the reaction?

What will be the value of Kc for the reverse reaction at the same temperature?

What would be the effect on Kc if temperature is increased​
