The feed system containing $10$kmo$\frac{l}{h}$ of ethylene, $60$kmo$\frac{l}{h}$ of benzene and $70$ kmo$\frac{l}{h}$ of toluene enters a partial condenser at $1$atm and $100C.$ Temperature is decreased to $55C$ at constant pressure. What are the compositions of vapor and liquid products?

$ln{P}^{**}=A-\frac{B}{T+C}$

$T[K],P^{**}[mmHg]$
