Question

For a reaction to occur spontaneously :
A. `Delta S` Must be negative
B. `(-Delta H_T Delta S)` must be postive
C. `Delta H+ Tdelta S ` must be negative
D. `Delta H` must be negative

Answer 1

Correct Answer - B
For spontaneous reaction
`Delta F=-ve`
`Delta G=DeltaH-TDeltaS`
`DeltaH-TDeltaS=-Ve`
OR
`-DeltaH +TDeltaS =+Ve`
