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. WebThe equilibrium constant for a reaction is calculated from the equilibrium concentrations (or pressures) of its reactants and products. If these concentrations are known, the calculation simply involves their substitution into the K expression, as was illustrated by this previous example.A slightly more challenging example is provided next, in which the reaction …
