$2)$ Temperature vs x$/$y and y vs x diagrams of MVC$-$LVC binary system at $760$ mmHg pressure is given below. By flash distillation, MVC and LVC will be separated from a feed stream containing $40$ mole percent MVC at $25\backslash$deg C$.$ Find

a$)$ the maximum MVC content of vapor and its temperature

b$)$ the maximum LVC content of liquid and its temperature

For different fractional vaporizations of $0\mathrm{.}25$ and $0\mathrm{.}75,$ find the followings:

c$)$ The temperature of flash chamber

d$)$ The recovery of MVC$.$
