Write the equilibrium constant expression for the reaction:
![Write the equilibrium constant expression for the reaction:
\[ \text{CaO}_{(s)} + \text{SO}_2{(g)} \rightleftharpoons \text{CaSO}_3{(s)} \]
### Explanation:
To write the equilibrium constant expression (\(K_c\)) for this reaction, we consider the concentrations of the gases and aqueous solutions only, as solids and liquids are not included in the equilibrium expression.
**Given Reaction:**
\[ \text{CaO}_{(s)} + \text{SO}_2{(g)} \rightleftharpoons \text{CaSO}_3{(s)} \]
**Equilibrium Constant Expression:**
For the reaction above, the equilibrium constant expression in terms of concentration (\(K_c\)) is simply:
\[ K_c = \frac{1}{[\text{SO}_2]} \]
Since both \(\text{CaO}\) and \(\text{CaSO}_3\) are solids, they are not included in the equilibrium constant expression. The only gaseous species involved is \(\text{SO}_2\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F1dd351b3-52c1-452a-96ee-ed63b06ec483%2Fb559e29a-d28b-4b7d-a3cd-d1438901a2b5%2F0bprcxn_processed.jpeg&w=3840&q=75)
