In an irreversible process taking place at constant `T` and `P` and in which only pressure-volume work is being done, the change in Gibbs free energy `(dG)` and the change in entropy `(dS)` satisfy the criteria

A

`( dS) _(V,E) gt 0 , (dG) _(T,P) lt 0`

B

`( dS) _(V,E) = 0 , (dG) _(T,P) = 0`

C

`( dS) _(V,E) = 0 , (dG) _(T,P) gt 0`

D

`( dS) _(V,E) lt 0 , (dG) _(T,P) lt 0`

In an irreversible process taking place at constant P and T in which only pressure volume work is being done by the system the change in Gibb's energy (DeltaG) and change in entropy (Delta) , satisfy the criterion:

Products are favored in a chemical reaction taking place at a constant temperature and pressure. Consider the following statements : (i) The change in Gibbs energy for the reaction is negative. (ii) the total change in Gibbs energy for the reaction and the surroundings is negative. (iii) The change in entropy for the reaction is positive. (iv) The total change in entropy for the reaction and the surrounding is positive. The statments which are ALWAYS true are :

Statement: The thermodynamics functions which determines the spontaneity of a process is the free energy. For a process to be spontaneous, the change in free energy must be negative. Explanation:The change in free energy is related to the change in enthalpy and change in entropy. the change in entropy for a process must be always positive if it is spontaneous.

A reversible heat engine carries 1 mole of an ideal monatomic gas aroung the cycle 1-2-3-1. Process 1-2 takes place at constant volume, process 2-3 take place at constant volume, process 2-3 is adiabatic, and process 3-1 takes place at constant pressure. Complete the values for the heat Delta Q , the change in internal energy Delta U , and the work done Delta , for each of the three processes and for the cycle as a whole.

Entropy ( S ) is a thermodynamic variable like pressure P , volume V and temperature T . Entropy of a thermodynamic system is a measure of disorder of molecular motion. Greater is disorder , greater is entropy. Change in entropy of a thermodynamic system is the ratio of heat supplied to absolute temperature.In an adiabatic reversible process, entropy remains constant while in any irreversible process entropy increases. In nature the processes are irreversible , therefore entropy of universe is continuoulsy increasing. After a long-long time, the energy available for work done will be :
