The Gibbs Free Energy

Gibbs Free Energy is a measure of the energy available in a system to do work, such as a chemical reaction. It considers internal energy, temperature, and entropy (disorder). When a process occurs spontaneously, Gibbs Free Energy decreases, indicating the system can release energy. If it increases, the process requires energy input. Think of it as the "usable energy" that drives reactions forward or backward, helping chemists predict whether a reaction will happen naturally under specific conditions. It’s a key concept for understanding and controlling chemical processes, energy flow, and system stability.
