Question

Which of the following is the correct representation of Gibbs’ Free Energy equation?

A) ∆G=∆H-T∆S
B) ∆G=∆H+T∆S
C) ∆G=∆S+T∆H
D) ∆G=∆S-T∆H

Answer 1

Answer: The correct answer is Option A.

Step-by-step explanation:

Gibbs' free energy is defined as the energy which is used to do work. It is represented as
`\Delta G`

It is also defined as the enthalpy change of the system minus the product of temperature and entropy change.

Mathematically,

`\Delta G=\Delta H-T\Delta S`

where,

`\Delta G` = Gibbs' free energy

`\Delta H` = Enthalpy change

`\Delta S` = Entropy change

T = absolute temperature

When
`\Delta G` comes out to be negative, the reaction is spontaneous and if comes out to be positive, the reaction is non-spontaneous.

Hence, the correct answer is Option A.

Answer 2

the correct representation of Gibbs’ Free Energy equation is
A) ∆G=∆H-T∆S
