Make a plot f this equation at intervals of Y of 0.1 and explain why the alternative form of the Rachford-Rice function in part (a) is not preferred. F4) = 21 i=1 f{Y} = zi(1-k;) 1 + 4(ki - 1) (c) Using the correct ' value estimated, find the vapor and liquid flow rates and composition for the flash column for a feed of 100 kmol/h
