हिन्दीIn the heterogeneous equilibrium \( \text{Ni}(\text{s}) + 4\text{CO}(\text{g}) \rightleftharpoons \text{Ni}(\text{CO})_4(\text{g}) \), which expression represents the equilibrium constant \( K_c \)?
Correct answer · Option 4
\( \frac{[\text{Ni}(\text{CO})_4]}{[\text{CO}]^4} \)
Explanation
The molar concentration of a pure solid like Ni(s) is constant and is incorporated into the equilibrium constant, giving \( K_c = \frac{[\text{Ni}(\text{CO})_4]}{[\text{CO}]^4} \).
