Question $2[20]$

Suppose you are given two parallel combustion reactions occurring in a fiow reactor: $C_3{H}_3+5O_{2}3C{O}_2+4H_{2}O(1)$ desired reaction

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

$(2)$ wndesired reaction

The reactor is fed with $250kmolh{r}_3{C}_4$ and $1500km\frac{o}{h}r{O}_2.$ The ext stream contains $45kmolhr{C}_3{H}_4,165kmolhrC{O}_2,450kmolh{r}^{C{O}_2},H_{2}O$ and $O_2.$ Determine the following:

$2\mathrm{.}1.$ Fractional conversion of $C_2{H}_4$

$(3$ 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 $($ext stream$).$

$(5$ marks$)$
