हिन्दीAt \( 1100\text{ K} \), the thermal decomposition of calcium carbonate \( \text{CaCO}_3(\text{s}) \rightleftharpoons \text{CaO}(\text{s}) + \text{CO}_2(\text{g}) \) has an equilibrium pressure of \( \text{CO}_2 \) equal to \( 2.0 \times 10^5\text{ Pa} \). In standard state pressure (\( 1\text{ bar} = 10^5\text{ Pa} \)), the dimensionless value of \( K_p \) is:
Correct answer · Option 4
\( 2.00 \)
Explanation
For heterogeneous equilibrium, \( K_p = p_{\text{CO}_2}/p^\circ = (2.0 \times 10^5\text{ Pa}) / (10^5\text{ Pa}) = 2.00 \).
