A reaction occurs spontaneously if

A

`T Delta S lt Delta H` and both `Delta H and Delta S` are +ve

B

`T Delta S gt Delta H` and both `Delta H and Delta S` are +ve

C

`T Delta S= Delta H` and both `Delta H and Delta S` are +ve

D

`T Delta S gt Delta H and Delta H` is +ve and `Delta S` is -ve

Text Solution

Verified by Experts

The correct Answer is:
B
For spontaneous reaction `DeltaG` should be negative `Delta G = Delta H- T Delta S = (+ve) - T (+ve)`
If `T Delta S gt DeltaH` then `Delta G` will be negative and reaction will be spontaneous at high temperature.
