Partial pressure in non-ideal solution (Given mole fraction,vapor pressure,fugacity coefficient)

Formula

$Partial pressure in non-ideal solution (Given mole fraction,vapor pressure,fugacity coefficient) formula$

the partial pressure of the component i in the mixture (in the solution)

the mole fraction of the component i in the ideal solution

pistar

the vapor pressure of the pure component i

phii

the fugacity coefficient (a correction for gas non-ideality)

gammai

the activity coefficient (a correction for interactions in the liquid phase between the different molecules)

Formula description

An ideal solution can be said to follow Raoult's Law but it must be kept in mind that in the strict sense ideal solutions do not exist. For a solution to be ideal we must assume that it does not matter whether a molecule A has another A as neighbor or a B molecule.
