Suppose you are given two parallel combustion reactions occurring in a flow reactor$-$

$C_3{H}_8+5O_{2}3C{O}_2+4H_{2}O(1)$ desired reaction

$C_3{H}_8+\frac{7}{2}{O}_{2}3CO+4H_{2}O$

$(1)$ desired reaction

$(2)$ undesired reaction

The reactor is fed with $250$kmo$\frac{l}{h}r{C}_3{H}_8$ and $1500$kmo$\frac{l}{h}rO.$ The exit stream contains $45$kmo$\frac{l}{h}r{C}_3{H}_8,165$kmo$\frac{l}{h}$rCO,$450$kmo$\frac{l}{h}rC{O}_2,H_{2}O$ and $O_2.$ Determine the following:

$2\mathrm{.}1.$ Fractional conversion of $C_3{H}_8$

$(3$ marks$)$

$2\mathrm{.}2.\%$ Excess $O_2$

$(4$ marks$)$

$2\mathrm{.}3.\%$Yield

$(4$ marks$)$

$2\mathrm{.}4.$ Selectivity

$(4$ marks$)$

$2\mathrm{.}5.$ Flowrates of $H_{2}O$ and $O_2$ from the reactor $($exit stream$).$

$(5$ marks$)$

THE END
