A hydrocarbon vapor$-$liquid mixture at $250\backslash$deg F and $500$ psia contains N$2,$ H$2$S$,$ CO$2,$ and all the normal

paraffins from methane to heptane. Use Figure $2\mathrm{.}4$ to estimate the K$-$value of each component in the

mixture. Which components will tend to be present to a greater extent in equilibrium vapor?Figure $2\mathrm{.}4$ Vapor$-$liquid equilibria, $40$ to $800F.$
