Which of the following equations relates Gibbs Free Energy to enthalpy and entropy?
ΔG = ΔH - TΔS
ΔG = TΔS - ΔH
ΔG = ΔH + TΔS
ΔG = ΔH / T + ΔS
The correct relation is ΔG = ΔH - TΔS.

Q: Which of the following equations relates Gibbs Free Energy to enthalpy and entropy?
Solution: The correct relation is ΔG = ΔH - TΔS.
Steps: 6
Step 1: Understand what Gibbs Free Energy (ΔG) is. It is a measure of the energy available to do work in a system at constant temperature and pressure.
Step 2: Know what enthalpy (ΔH) is. It represents the total heat content of a system.
Step 3: Learn about entropy (ΔS). It is a measure of the disorder or randomness in a system.
Step 4: Recognize that the relationship between these three concepts is expressed in an equation.
Step 5: The equation that connects Gibbs Free Energy, enthalpy, and entropy is ΔG = ΔH - TΔS.
Step 6: In this equation, T represents the absolute temperature in Kelvin.
