In reversible adiabatic process DeltaS is

In a reversible process, if changes in entropy of the system and its surroundings are DeltaS_(1) & DeltaS_(2) respectively, then-

The change in entropy in.a reversible adiabatic process is —

If the process AtoB occurs reversible, then the change in entropy of the system be, DeltaS_(1) . When the same process occurs irreversible, the change in entropy of the system be DeltaS_(2) . Will the value of DeltaS_(1) be greater than, less than or equal to the value of DeltaS_(2) ?

This question has Statement I and Statement II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I : Entropy change in reversible adiabatic expansion of an ideal is zero. Statement-II : The increase in entropy due to volume increase just compensate the decrease in entropy due to fall in temperature.

(i) Spontaneity of a process can be determined from the entropy change and also from the Gibbs free energy change. But the Gibbs free energy change in more useful than entropy change to determine the spontaneity of a process. Explain it. (ii) Show that Gibbs energy change of a system at certain temperature and pressure, DeltaG=DeltaH-TDeltaS .

If the change in entropy of reversible isothermal expansion of 1 mol of an ideal gas is 9.135 " J mol"^(-1). K^(-1) , what will be the entropy change of the surroundings and universe ? If the above expansion of gas is allowed to occur against zero pressure, what will be the entropy change of the system and surroundings ?

The initial state of 1 mol of an ideal gas is (P_(1),V_(1),T_(1)) . The gas is expanded by a reversible isothermal process and also by a reversible adiabatic process separately. If final volume of the gas is same in both the processes, and changes in internal energy in the isothermal and adiabatic processes are DeltaU_(1) and DeltaU_(2) respectively, then-

A process is always spontaneous at all temperature if the enthalpy change is ___ and entropy change is _____.
