Consider the formation of phosphorus pentachloride from phosphorus trichloride and chlorine gas: PCl3 (g) + Cl2 (g) <---> PCl5 (g) If the equilibrium constant at a certain temperature is Kc = 1.36, what will the equilibrium concentration of PCl5 (g) be if the initial concentrations of the two reactant gases was each 0.450 M and that of the product was 0.100 M? (Note - the value of Q for the initial concentrations is 0.494, which is just a little below the value of Keq - although the reaction will proceed toward products, the final concentration of PCl5 will not increase very much).
