SUMMARY
The equilibrium constant Kc for the reaction PCl3 (g) + Cl2 (g) = PCl5 (g) is established at 49 at 230°C. When 0.400 mol of both phosphorus trichloride and chlorine are introduced into a 4.0-liter reaction vessel, the equilibrium composition can be calculated using the Kc value. This involves determining the changes in concentration of the reactants and products at equilibrium. The final concentrations of PCl3, Cl2, and PCl5 can be derived from the initial concentrations and the stoichiometry of the reaction.
