Answer 1

Explanation:

Gibbs Function:

Also known as the Gibbs free energy, Gibbs energy, or Free Enthalpy, is a quantity that is used to measure the maximum amount of work done in a thermodynamic system when the temperature and pressure are kept constant.
Gibb's free energy is denoted by the symbol ‘G’. Its value is usually expressed in Joules or Kilojoules.
Gibb's free energy can be defined as the maximum amount of work that can be extracted from a closed system.

Gibbs Free Energy Equation:

G = H – TS

Where, G = Gibbs free energy, H = enthalpy, T = temperature, S = entropy

⇒ G = U + PV – TS

Where, U = Internal energy, P = Pressure, V = Volume, T = Temperature, S = Entropy

Additional Information

ΔG = ΔH – TΔS

This equation is called the Gibbs Helmholtz equation.

ΔG > 0; the reaction is non-spontaneous and Endergonic.

ΔG < 0; the reaction is spontaneous and Exergonic.
