An equal amount of nitrogen $(N_2)$ and oxygen $(O_2)$ are initially fed to a reactor and react

according the following equation:

$\frac{1}{2}{N}_2(g)+\frac{1}{2}{O}_2(g)>NO(g)$

At $1200K$ and $10$ bar.

a$)$ Calculate the equilibrium conversion of $N_2$ and $O_2.$

b$)$ Re$-$calculate $($a$)$ at pressure of $20$ bar.

c$)$ Discuss on the influence of pressure on the conversion of $N_2$ and $O_2.$
