Standard Gibbs Free Energy Change

Standard Gibbs Free Energy Change (ΔG°) is a measure of the energy difference between reactants and products in a chemical reaction under standard conditions (such as specific temperature and pressure). It indicates whether a reaction can spontaneously occur: a negative ΔG° means the reaction is likely to happen naturally, releasing energy, while a positive ΔG° suggests it requires energy input to proceed. It helps chemists predict reaction direction and feasibility, playing a key role in understanding processes like energy transfer, biological functions, and industrial reactions.
