Question

Define Entropy and give its relation with free energy

Answer 1

Answer:

Gibbs free energy combines enthalpy and entropy into a single value.

Gibbs free energy is the energy associated with a chemical reaction that can do useful work. It equals the enthalpy minus the product of the temperature and entropy of the system.

G = H – TS

At constant temperature

ΔG = ΔH – TΔS

ΔG predicts the direction of a chemical reaction. If ΔG is negative, then the reaction is spontaneous. If ΔG is positive, then the reaction is non-spontaneous.

Answer 2

Answer:

heya here is ur answer mate

Explanation:

Gibbs free energy combines enthalpy and entropy into a single value.

Gibbs free energy is the energy associated with a chemical reaction that can do useful work. It equals the enthalpy minus the product of the temperature and entropy of the system.

G = H – TS

At constant temperature

ΔG = ΔH – TΔS

ΔG predicts the direction of a chemical reaction. If ΔG is negative, then the reaction is spontaneous. If ΔG is positive, then the reaction is non-spontaneous.
