<u>1. Write the solubility equation:</u>
- CaCO₃(s) ⇄ Ca²⁺(aq) + CO₃²⁻
<u>2. Write the concentrations below the equation:</u>
- CaCO₃(s) ⇄ Ca²⁺(aq) + CO₃²⁻
A - s s s
<u>3. Write the Ksp equation:</u>
- Ksp = [Ca²⁺] . [CO₃²⁻] ↔ the solid substances do not appear
- Ksp = s × s
- 4.5 × 10⁻⁹ = s²

Answer: (a) The reaction mixture will proceed toward products.
Explanation:
Equilibrium constant is defined as the ratio of pressure of products to the pressure of reactants each raised to the power their stoichiometric ratios. It is expressed as
K is the constant of a certain reaction when it is in equilibrium, while Q is the quotient of activities of products and reactants at any stage other than equilibrium of a reaction.
For the given chemical reaction:
The expression for is written as:
Thus as , the reaction will shift towards the right i.e. towards the product side.
