A mixture containing nitrobenzene, aniline, water and hydrogen is fed to the partial condenser at $1$atm and $117C.$ It contains $5$ kmol$/$h of nitrobenzene, $95$ kmol $/$h of aniline, $715$ kmol$/$h of hydrogen and $190$kmol$/$h of water. All ofhydrogen and some part of condensable components are separated as vapor product. The exit temperature of partial condenser is $45C.$

a$.$ Write model equations and obtain an expression to find V$/$F$.$

b$.$ Calculate V$/$F ratio using Newton Raphson method.

c$.$ Calculate vapor and liquid product distributions of partial condenser.
