The K value of a component in vapour liquid equilibrium is

  • A.the amount in the vapour over the amount in the feed
  • B.its liquid mole fraction over its vapour mole fraction
  • C.the moles of vapour formed per mole of liquid remaining
  • D.its vapour mole fraction over its liquid mole fraction

Answer: D

It is the distribution ratio between the phases and is the working quantity in every flash calculation. For an ideal system it reduces to the vapour pressure divided by the total pressure, but in general it depends on composition too.
