For which of these processes is the value of `Delta S` negative?
i. Sugar is dissolved in water.
ii. Steam condenses on a surface.
iii. `CaCO_(3)` is decomposed into `CaO` and `CO_(2)`.

For which of these processes is the value of DeltaS negative I. Sugar is dissolved in water. II. Steam condenses on a surface III. CaCO_3 is decomposed into CaO and CO_2

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

Predict the sign of DeltaS for the reaction : CaCO_(3)(s) overset(Delta) to CaO(s) + CO_(2)(g)

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) .

Identity the endothermic and exothermic reaction. CaCO_(3(s)) overset(Delta)rarr CaO_((s))+CO_(2) uarr

Identity the endothermic and exothermic reaction. CaCO_(3(s)) overset(Delta)rarr CaO_((s))+CO_(2) uarr
