Minimum work (W) required to separate a binary gas mixture at a temperature T0 and pressure P0 is W=-RT0[y1ln( f01/fpure,1)+y2ln( f02/fpure,2)] where y1 and y2 are mole fractions, fpure,1 and fpure,2 are fugacities of pure species at T0 and P0, and f01 and f02 are fugacities of species in the mixture at T0 P0 and y1. If the mixture is ideal then W is
Correct : b
