Change in Gibbs free energy (given change in enthalpy, temperature and change in entropy)
change in Gibbs free energy
change in enthalpy
change in entropy
In thermodynamics, the Gibbs free energy (also known as free enthalpy to distinguish it from Helmholtz free energy) is a thermodynamic potential that measures the `useful` or process-initiating work obtainable from a thermodynamic system at a constant temperature and pressure (isothermal, isobaric).
