The reaction between ethylene and hydrogen bromide to form ethyl bromide is carried out in a continuous reactor.

The product stream is analyzed and found to contain $58\mathrm{.}7$ mol$\%C_2{H}_{5}Br$ and $13\mathrm{.}3$mol$\%HBr.$

The feed to the reactor conains only ethylene and hydrogen bromide.

Calculate the fractional conversion of the limiting reactant and the percentage by which the other reactant is in excess.

If the molar flow rate of the feed stream is $205mo\frac{l}{s},$ what is the extent of reaction?

Fractional Conversion: $$

Percent Excess of non$-$limiting reactant: $\%$

Extent of reaction: $$
