Gibbs free energy (F) is defined as__________________?
Correct answer: B. F = H - TS
- A. F = E - TS
- B. F = H - TS
- C. F = H + TS
- D. F = E + TS
Explanation
Gibbs free energy is defined as G = H - TS, where H is enthalpy, T is absolute temperature, and S is entropy. The expression F = E - TS instead defines Helmholtz free energy, so the symbol F in the question is a notation error.
