For an ideal liquid solution, which of the following is unity ?
Correct answer: C. Activity co-efficient
- A. Activity
- B. Fugacity
- C. Activity co-efficient
- D. Fugacity co-efficient
Explanation
For an ideal liquid solution, each component obeys Raoult's-law behaviour, so its activity coefficient is unity. The activity itself usually equals the component mole fraction and is not generally one.
