Methane and steam are fed to a reactor in molar ratio $1$:$3.$ The following reaction takes place,

$(6$M$)$

$C{H}_4(g)+2H_{2}O(g)C{O}_2(g)+4H_2(g)$

$C{H}_4(g)+H_{2}O(g)CO(g)+3H_2(g)$

Where $C{O}_2$ is the desired product, $CO$ is the undesired product and $H_2$ is a byproduct. The exit steam has the following composition
