In an irreversible process taking place ...

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:

A

`(DeltaS)_(V.U)=0,(DeltaG)_(T.P)=0`

B

`(DeltaS)_(V.U)=0,(DeltaG)_(T.P)=+ve`

C

`(DeltaS)_(V.U)=0,(DeltaG)_(T.P)=-ve`

D

`(DeltaS)_(V.U)=0,(DeltaG)_(T.P)=-ve`

Text Solution

Verified by Experts

The correct Answer is:
C
For a spontaneous change (work is being done by the system) `(dG)_(T,P)=-ve` and `(dS)_(V,U)=+ve`

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 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.
