Which of the following relation is true between Gibbs energy, enthalpy, temperature, and entropy?(a) G = H -TS(b) G = H -T(c) G = H -S(d) G = -TSI have been asked this question during a job interview.My question comes from Thermodynamics topic in division Thermodynamics of Chemistry – Class 11

Answer» RIGHT option is (a) G = H -TS

The best explanation: The energy that is available for a system at some CONDITIONS and by which useful work can be done is Gibbs FREE energy. The relation between Gibbs free energy, enthalpy, temperature and entropy is GIVEN by Gibbs Helmholtz equation; G = H -TS.
