Gibbs Free Energy

Gibbs Free Energy Definition:

The ultimate arbiter of the spontaneity of a reaction, where DG = DH – T DS.

Gibbs Free Energy Explained:

It is represented as G=H-TS where (H),(T), and (S) are enthalpy, temperature, and entropy. The SI unit of Gibbs energy is in kilojoules (KJ). The changes that take place in Gibbs energy refers to the free energy subjected constant temperature and pressure.
