The thermal dissociation equilibrium $$CaCO_{3}(s)$$ is studied under different conditions.
$$CaCO_{3}(s)\rightleftharpoons CaO(s)+CO_{2}(g)$$

A

$$\triangle H$$ is dependent on T

B

K is independent of the initial amount of $$CaCO_{3}$$

C

Kis dependenton the pressure of $$CO_{2}$$ at a given T

D

$$\triangle H$$ is independentof the catalyst, if any
