For a given substance at a specified temperature, activity is ______________ to fugacity?
Correct answer: B. Directly proportional
- A. Inversely proportional
- B. Directly proportional
- C. Equal
- D. None of these
Explanation
Activity is defined from fugacity as a = f/f° at a specified temperature and standard-state fugacity f°. Since f° is fixed under the stated conditions, activity is directly proportional to fugacity.
