Chemistry - Chemical Equilibrium Question with Solution | TestHub

Consider the following heterogeneous equilibrium, ${\mathrm{CaCO}}_3(\mathrm{s})\rightleftharpoons \mathrm{CaO}(\mathrm{s})+{\mathrm{CO}}_2(\mathrm{g})$. At $800^{\circ }\mathrm{C}$, the pressure of ${\mathrm{CO}}_2$ is 0.236 atm . The value of ${\mathrm{K}}_{\mathrm{c}}$ for the above given equilibrium reaction at this temperature is
