The thermal dissociation equilibrium of  ${\mathrm{CaCO}}_3\left(s\right)$ is studied under different conditions ${\mathrm{CaCO}}_3\left(s\right)\rightleftharpoons \mathrm{CaO}\left(s\right)+{\mathrm{CO}}_2\left(g\right)$ For this equilibrium, the correct statement(s) is (are)

${\mathrm{CaCO}}_{3\left(s\right)}\rightleftharpoons {\mathrm{CaO}}_{\left(s\right)}+{\mathrm{CO}}_{2\left|g\right|}{K}_P={\left(P_{{\mathrm{CO}}_2}\right)}_{\text{atequilibrium }}$ For a given reaction. $K_{eq}$ depends only on temperature.

$K_{eq}$ depends only on temperature. Enthalpy of reaction is independent of the catalyst. Catalyst generally changes activation energy.
