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.

Answer the following questions based on the P – T phase diagram of CO_(2) : (a) CO_(2) at 1 atm pressure and temperature – 60^(@)C is compressed isothermally. Does it go through a liquid phase ? (b) What happens when CO_(2) at 4 atm pressure is cooled from room temperature at constant pressure ? (c) Describe qualitatively the changes in a given mass of solid CO_(2) at 10 atm pressure and temperature –65^(@)C as it is heated up to room temperature at constant pressure. (d) CO_(2) is heated to a temperature 70^(@)C and compressed isothermally. What changes in its properties do you expect to observe ?
