MCQ
For an ideal liquid solution, which of the following is unity?
  • ✓
    Activity coefficient
  • B
    Fugacity coefficient
  • C
    Fugacity
  • D
    Activity
✓

Answer

Correct option: A.
Activity coefficient
An activity coefficient is a factor used in thermodynamics to account for deviations from ideal behavior in a mixture of chemical substances.
Hence, for an ideal liquid solution, that deviation is $0,$ as the mole fraction of other substance is $0.$
