When `CaCO_(3)` is heated to a high temperature, it undergoes decomposition into `CaO` and `CO_(2)` whereas it is quite stable at room temperature. The most likely explanation of its is

A

The enthalpy of reaction `(DeltaH)` overweighs the term `T DeltaS` at high temperature.

B

The term `T DeltaS` overweights the enthalpy of reaction at high temperature

C

At high temperature, both enthalpy of reaction and entropy change becomes negative.

D

None of these.

Gibbs Helmholtz equation relates the enthalpy, entropy and free energy change of the process at constant pressure and temperature as DeltaG=DeltaH-TDeltaS " (at constant P, T)" In General the magnitude of DeltaH does not change much with the change in temperature but the terms TDeltaS changes appreciably. Hence in some process spontaneity is very much dependent on temperature and such processes are generally known as entropy driven process. When CaCO_(3) is heated to a high temperature it decomposes into CaO and CO_(2) , however it is quite stable at room temperature. It can be explained by the fact that

A: H_(2) when allowed to expand at room temperature it causes heating effect. R: H_(2) has inversion-temperature much below room temperature.
