A process is taking place at constant temperature and pressure. Then

A

`Delta H= Delta E`

B

`Delta H= T Delta S`

C

`Delta H= 0`

D

`Delta S= 0`

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta G= Delta H- T Delta S`
`Delta G = Delta H- T Delta S`
at constant temperature and pressure `Delta G=0`
`0= Delta H - T Delta S " so " Delta H= T Delta S`
