For a spontaneous process, the change in Gibbs free energy (ΔG) is related to entropy (ΔS) by which of the following equations?

Step 1: Understand that Gibbs free energy (ΔG) is a measure of the energy available to do work in a system.
Step 2: Know that for a process to be spontaneous, it must occur without needing to be driven by an external force.
Step 3: Recognize that the change in Gibbs free energy (ΔG) is related to the change in enthalpy (ΔH) and the change in entropy (ΔS).
Step 4: Learn the equation that relates these quantities: ΔG = ΔH - TΔS, where T is the temperature in Kelvin.
Step 5: Remember that for a process to be spontaneous, ΔG must be negative (ΔG < 0).

Gibbs Free Energy – Gibbs free energy (G) is a thermodynamic potential that measures the maximum reversible work obtainable from a system at constant temperature and pressure.
Spontaneous Processes – A spontaneous process is one that occurs without external intervention, typically characterized by a decrease in Gibbs free energy (ΔG < 0).
Entropy – Entropy (S) is a measure of the disorder or randomness in a system, and its change (ΔS) is a key factor in determining the spontaneity of a process.
Enthalpy – Enthalpy (H) is a measure of the total heat content of a system, and its change (ΔH) is also important in the Gibbs free energy equation.
