Question

The thermal dissociation equilibrium of $\mathrm{CaCO}_{3(s)}$ is studied under different conditions.\ $\mathrm{CaCO}_{3(s)} ightleftharpoons \mathrm{CaO}_{(\mathrm{s})}+\mathrm{CO}_{2(\mathrm{~g})}$\ For this equilibrium, the correct statement(s) is (are)\

Professor PC Thomas Classes · Answer

(a,b,d) : $\mathrm{CaCO}_{3(s)} ightleftharpoons \mathrm{CaO}_{(s)}+\mathrm{CO}_{2(g)}$ The equilibrium constant $(K)$ is independent of the initial amount of $\mathrm{CaCO}_{3}$ whereas at a given temperature, it is independent of pressure of $\mathrm{CO}_{2} . \Delta H$ is independent of catalyst and it depends on temperature.\
