What describes the change in gibbs free energy (∆g) of a spontaneous reaction? a. ∆g < 0 b. ∆g > 0 c. ∆g = 0

The correct answer is Option A.

Explanation:

Gibbs Free energy is defined as amount of useful work that can be done in the system. It is equal to the enthalpy of the reaction minus the product of entropy of the reaction and absolute temperature.

Mathematically,

Where,

= Gibbs free energy

= Enthalpy of the reaction

= Entropy of the reaction

T = Absolute temperature

Sign Convention for Gibbs Free energy:

If , it is considered as a Spontaneous reaction.

If , it is considered as a Non-Spontaneous reaction.

If , reaction is in equilibrium.

Hence, the correct answer is Option A.
