Expert Solution
Step 1: Rules of writing equilibrium constant expression
Equilibrium constant Kc for a reaction is defined as the product of the equilibrium molar concentrations of the products, each raised to the power equal to a stoichiometric coefficient divided by the product of the equilibrium molar concentrations of the reactant each raised to the power equal to its stoichiometric coefficient .
& the most important convention to be kept in mind is that the active mass of a pure solid or pure liquid is considered to be constant.
