Write the equilibrium constant expression for the following reactions :
` BaSO_4(s) hArr Ba^(2+) (aq) +SO_4^(2-) (aq) `

Explanation

To write the equilibrium constant expression for the reaction:

\[ \text{BaSO}_4(s) \rightleftharpoons \text{Ba}^{2+}(aq) + \text{SO}_4^{2-}(aq) \]

we follow these steps:

### Step 1: Identify the Products and Reactants
In the given reaction, the products are \(\text{Ba}^{2+}(aq)\) and \(\text{SO}_4^{2-}(aq)\), while the reactant is \(\text{BaSO}_4(s)\).
