Which of the following conditions may lead to a non-spontaneous change?
A
`DeltaH " and "DeltaS " both "+ve`
B
`DeltaH=-ve,DeltaS=+ve`
C
`DeltaH=+ve,DeltaS=-ve`
D
`DeltaH=-ve,DeltaS=-ve`
Text Solution
Verified by Experts
The correct Answer is:
A, C, D
`DeltaG=DeltaH-TDeltaS` `(a) DeltaH=+ve,DeltaS=+ve` at low temperature `DeltaG=+ve` (b) `DeltaH=-ve,DeltaS=+ve, DeltaG=-ve` at any temperature. `(c )DeltaH=+ve, DeltaS=-ve, DeltaG=+ve` at any temperature (d) `DeltaH=-ve, DeltaS=-ve, DeltaG=+ve` at high temperature
