Which of the following expression defines the physical significance of free energy change?

A

`-DeltaG=w_((non-exp))`

B

`-DeltaG=-w_((non-exp))`

C

`DeltaG= -w_((exp))`

D

`DeltaG= w_((exp))`

Text Solution

Verified by Experts

The correct Answer is:
B
Decrease in free energy `(-DeltaG)` equals to useful work done by the system `(-W_(non-exp))`.
