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).

Answer»

`DeltaH` is dependent on T
K is independent of the initial AMOUNT of `CaCO_3`
K is dependent on the pressure of `CO_2` at a GIVEN T
