The thermal dissociation equilibrium of `CaCO_(3)(s)` is studied under different conditions
`CaCO_(3)(s)hArrCaO(s)+CO_(2)(g)`
For this equilibrium, the correct statements are
(i) K is dependent on the pressure of `CO_(2)` at a given T.
(ii) `Delta H` is dependent on T.
(iii) `Delta H` is independent of the catalyst, if any.
(iv) K is independent of the initial amount of `CaCO_(3)`.

Options

A. `DeltaH` is dependent on T
B. K is independent of the initial amount of `CaCO_3`
C. K is dependent on the pressure of `CO_2` at a given T
D. `DeltaH` is independent of the catalyst , if any
