How to solve for the equilibrium expression

WebThe equilibrium constant expression is now written as follows. Each of these equilibrium constant expressions is the inverse of the other. We can therefore calculate Kc by dividing Kc into 1. We can also calculate equilibrium constants by combining two or more reactions for which the value of Kc is known. WebSolution. Use the stepwise process described earlier. Identify the direction in which the reaction will proceed to reach equilibrium. The balanced equation for the decomposition of PCl5. P C l 5. is. PCl5 (g) ⇌ PCl3 (g) + Cl2 (g) P C l 5 ( g) ⇌ P C l 3 ( g) + C l 2 ( g) Because only the reactant is present initially Qc = 0.
