EXERCISE $2$

A gas mixture with the following composition $30\%CO,10\%C{O}_2,10\%H_2$

and the rest $N_2$ is used in a carburization furnace at $927C.$ Calculate the

equilibrium gas mixture composition if the total pressure is $1$ atm.

Assume that all gases behave ideally and that only $C{O}_2$ and $H_2$ is formed

as products.

Given:

$+\frac{1}{2}{O}_2=CO,G=-111713-87\mathrm{.}86T$ Joules

$+O_2=C{O}_2,G=-394133-0\mathrm{.}84T$ Joules

$H_2+\frac{1}{2}{O}_2=H_{2}O,G=-246438+54\mathrm{.}39T$ Joules
