Gibbs free energy of a pure fluid approaches _____________ as the pressure tends to zero at constant temperature?
Correct answer: B. Minus infinity
- A. Infinity
- B. Minus infinity
- C. Zero
- D. None of these
Explanation
For a pure fluid at constant temperature, the chemical potential or molar Gibbs energy contains the term RT ln f. As pressure and fugacity approach zero, ln f approaches minus infinity, so the Gibbs free energy does also.
