Question $1)(28$ pMethanol is synthesized by reacting $CO$ and $H_2.$ A fresh feed stream $(n_1)$ containing $35$ mol $CO$ and

$h_1$ mole $H_2$ joins a recycle stream $(n_3).$ The combined stream $(n_2)$ is fed to a reactor. The reactor outlet stream flows at $350$

$mo\frac{l}{m}in$ and contains $63$ mole $\%H_2,27$ mole $\%CO$ and $10$ mole $\%C{H}_{3}OH.$ This stream is split into two fractions: One

is removed from the process $(n_4)$ and the other one is the recycle stream $(n_3)$ that combines with the fresh feed.

Calculate $n_1,n_2,n_3,n_4,x_1,y_1,z_1.$
