Question $1.(30$ pts$)$ What kind of reactor or a reactor scheme and operation temperature $($high

or low$)$ should be used to increase the selectivity of $C{H}_{3}C{H}_{3}OH$ over $C{H}_2=C{H}_2$ for the

following reactions:

The orders of the reactions are $1$ with respect to KOH for both reactions and it is $0\mathrm{.}5$ and $1$ with

respect to $C{H}_{3}C{H}_{2}Br$ for the first and second reactions, respectively. The activation energy of

the first reaction is $2000$kca$\frac{l}{m}$ole and that of the second reaction is $300$kca$\frac{l}{m}$ole. The

Arrhenius constant for the first reaction is $800$ and that for the second reaction is $10.$
