The standard state of a gas (at a given temperature) is the state in which fugacity is equal to__________________?
Correct answer: C. Both A. & B
- A. Unity
- B. Activity
- C. Both A. & B
- D. Neither A. nor B
Explanation
A standard state is the reference state for which the normalized fugacity and activity are taken as unity. Fugacity technically carries pressure units, so this statement uses the usual convention of measuring it relative to the standard pressure.
