Question

How to calculate ΔG (free energy) using enthalpy ΔH and entropy ΔS values?"

A) ΔG = ΔH - TΔS
B) ΔG = ΔH + TΔS
C) ΔG = ΔH / TΔS
D) ΔG = TΔS - ΔH

Answer 1

The formula for calculating the change in Gibbs free energy (ΔG) using enthalpy (ΔH) and entropy (ΔS) values is ΔG = ΔH - TΔS.

Step-by-step explanation:

The formula for calculating the change in Gibbs free energy (ΔG) using enthalpy (ΔH) and entropy (ΔS) values is:

ΔG = ΔH - TΔS

This equation shows that the change in Gibbs free energy is equal to the change in enthalpy minus the product of the temperature and the change in entropy.
