हिन्दीIn the heterogeneous reaction \( \text{Ag}_2\text{O}(\text{s}) + 2\text{HNO}_3(\text{aq}) \rightleftharpoons 2\text{AgNO}_3(\text{aq}) + \text{H}_2\text{O}(\text{l}) \), which species appear in the expression for \( K_c \)?
Correct answer · Option 2
\( \text{AgNO}_3(\text{aq}) \) and \( \text{HNO}_3(\text{aq}) \) only
Explanation
Pure solid \( \text{Ag}_2\text{O}(\text{s}) \) and pure liquid solvent \( \text{H}_2\text{O}(\text{l}) \) have constant concentrations, so \( K_c = \frac{[\text{AgNO}_3]^2}{[\text{HNO}_3]^2} \).
