Question

Initially, 0.8 mol of P C l 5 and 0.2 mol of P C l 3 are mixed in a one litre vessel. At equilibrium, 0.4 mol of P C l 3 is present. The value of K c for the reaction, P C l 5 g ⇌ P C l 3 g + C l 2 g , would be, 0.13 mol L - 1, 0.66 mol L - 1, 0.013 mol L - 1, 0.05 mol L - 1

MARKS App · Accepted Answer

So x = 0.2 K c = P C l 3 C l 2 P C l 5 = 0.4 × 0.2 0.6 = 0.13 mol L - 1
