If 13.9 % of a 1.0 mol/L concentration of phosphorus pentachloride decomposes, find the value of Keq. PCl5(g) ⇌ PCl3(g) + Cl2(g) MR 1 1 1 I 1.0 0 0 C -x +x +x E 1.0-x x x At equilibrium, 13.9% of PCl5 is decomposed. Therefore the Keq value is 2.24 x 10-2. The substance AO2 is 10.0 % molar dissociated according to the following reaction. ................
