Consider the isothermal, isobaric gas$-$phase reaction

$2$A$+$B$$C$+1\mathrm{.}5$ D

The temperature is $313\backslash$deg C and the pressure is $12\mathrm{.}2$ atm. The feed stream contains $0\mathrm{.}4$ mol A$/$mol and $0\mathrm{.}3$ mol B$/$mol$,$ with

the remaining $0\mathrm{.}3$ mol$/$mol being inert species $(0.$

$($a$)$ Generate a complete stoichiometric table $.$ Include a column for the concentration of each species leaving the reactor. Define conversion in terms of B $($XB$)$

$($b$)$ Plat the concentration of A$,$ B$,$ C$,$ D$,$ and I leaving the reactor as a function of the conversion of $8.$ The x$-$axis should range from $0$ to $1.$ What is the maximum concentration of D leaving the reactor?

$($c$)$ Consider the situation where the feed stream contains $0\mathrm{.}4$ mol A$/$mol and $0\mathrm{.}2$ mol B$/$mol$,$ with the remaining $0\mathrm{.}4$ mol$/$mol being inert species $(/).$ On a new graph, plot the concentration of A$,$ B$,$ C$,$ D$,$ and I leaving the reactor as a function of the conversion of B$.$ What is the maximum concentration of D leaving the reactor? Would you choose

to operate the process with the original feed composition $($above$)$ or the one presented in $($c$)?$ Explain your decision,
