Problem 4 (7.47 of Koretsky 2nd edition) A binary mixture of species 1 and 2 can be described by the following equation of state: P=vRTv3Ta The pure species coefficients are given by: amix=y1a1+a2y2 with the mixing rule: a1=800[(Jm1.5K0.5)/mol1.5]anda2=500[(Jm1.5K0.5)/mol15] Consider a vapor mixture of 1 mole of species 1 and 2 moles of species 2 that occupies a volume of 6L at 500K. (a) Determine the fugacity coefficient of component 1 in the mixture, ^1 (b) By how much does your answer change if you approximate the solution using the Lewis fugacity rule instead
