Consider the hydrogenation of $1-$butene to butane by the following reaction:

$C_4{H}_8(g)+H_2(g)C_4{H}_{10}(g)$

The feed flow ratio is $10$ moles of $H_2$ per mole of $C_4{H}_8.$ Consider a reactor temperature of $1000K$ and

reactor pressure of $5$ bar. Calculate the ratio of butane:$1-$butene at equilibrium. You may assume ideal gas

behavior and that $h_{rxn}^o$ is independent of temperature. Data from appendix A$.3$ is provided below for

your convenience.
