Question

The accompanying diagram represents a reversible cannot cycle for an ideal gas:

What is the Gibbs free energy change during the process `A rarr B` ?
A. 150 KJ
B. `-150 KJ`
C. 30 KJ
D. data are not sufficient

Answer 1

Correct Answer - B
`DeltaG=DeltaH-TDeltaS " " implies " "DeltaH=0, DeltaS = 150 JK^(-1) " " implies " " DeltaG=-150 KJ`
