Gibbs energy of Gibbs function, `G`, is defined as

A

`G = U + TS`

B

`G = H - TS`

C

`G = H + TS`

D

`G = U - TS`

Text Solution

Verified by Experts

The correct Answer is:
B
Gibbs energy is the part of total energy which is available for doing useful work. `H` stands for total energy of the system while `TS` stands for energy for nonuseful work (or the energy which is not available to do useful work).
