The thermal dissociation of equilibrium of `CaCo_(3)(s)` is studied under different conditions
`CaCO_(3)(s)hArrCaO(s)+CO_(2)(g)`
For this equilibrium, the correct statement (s) is/are

The thermal dissociation equilibrium of CaCO_(3)(s) is strudied 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 inintial amount of CaCO_(3) .

For the reaction : CaCO_(3) (s) hArr CaO (s) + CO_(2) (g)

The reaction CaCO_(3)(s) hArr CaO(s)+CO_(2)(g) reaches the state of equilibrium when
