Gibbs Free Energy

Calculate ΔG=ΔH-TΔS and spontaneity

Gibbs Free Energy (ΔG=ΔH-TΔS)

Gibbs free energy (G) determines whether a chemical reaction can occur spontaneously at constant temperature and pressure. ΔG = ΔH − TΔS: negative ΔG means spontaneous; positive means non-spontaneous.

Fun Fact

Josiah Willard Gibbs developed this function in 1873–1876 — arguably the most significant contribution to chemistry in the 19th century, enabling prediction of chemical equilibria.
