Activity coefficients at infinite dilution are valuable because they

  • A.hold good over any range of composition
  • B.fix model parameters at the most non-ideal point
  • C.are a good deal easier to compute than they are to measure
  • D.are equal to one for every real system there is

Answer: B

The dilute end is where deviations are largest, so a measurement there constrains a model strongly. Several experimental techniques exist specifically to obtain these limiting values. Gas chromatography is one of the more convenient of them.
