Question

Write the expression for the equilibrium constant for the reaction represented by the equation

CaCO3(s) ⇌ Ca2+(aq) + CO3 −(aq). Is Kc > 1, < 1, or ≈ 1? Explain your answer.

Answer 1

Equilibrium constant is the ratio of the product of the concentrations of the products raised to their corresponding stoichiometric coefficients to that of the reactants. This is only applicable for aqueous components. Solids and liquids have constant of 1. In this case,Kc would always have to be greater than 1.
