Sahay Sir > Question Answers > equilibrium constant Kc for decomposition of phosphorus pentachloride
At 473 K, equilibrium constant Kc for decomposition of phosphorus pentachloride, PCl5 is 8.3×10^−3 . If decomposition is depicted as, PCl 5(g)⇌PCl 3(g)+Cl2(g) Δ rH ⊖ = 124.0 kJ mol^−1 (a) Write an expression for Kc for the reaction. (b) What is the value of Kc for the reverse reaction at the same temperature? (c) What would be the effect on Kc if (i) more PCl5 is added (ii) pressure is increased (iii) the temperature is increased ?
