A system of propane and n-butane exists in two-phase vapor/liquid equilibrium at 10.0
A system of propane and n-butane exists in two-phase vapor/liquid equilibrium at 10.0
bar and 323 K.The mole fraction of propane is about 0.67 in the vapor phase and about
0.40 in the liquid phase.Additional pure propane is added to the system,which is brought
again to equilibrium at the same T and P,with both liquid and vapor phases still present.
What is the effect of the addition of propane on the mole fractions of propane in the
vapor and liquid phases?
