The liquid phase reaction between methyl bromide and potassium iodide has been found to be first order with respect

to each reactant.

$C_2{H}_{4}B{r}_2+3KI{C}_2{H}_4+2KBr+K{I}_3$

a$)$ Set up a stoichiometric table for a batch system. If the initial mixture consisted solely of methyl bromide at a

concentration of $0\mathrm{.}0266M$ and potassium iodide at a concentration of $0\mathrm{.}2237M,$ calculate the concentration of

species when the conversion is $75\%.$

b$)$ In a $5L$ batch reactor, the conversion of the methyl bromide was $0\mathrm{.}591$ after $15\mathrm{.}25$ hours. Determine the value of

the rate constant.

c$)$ Set up a stoichiometric table for a flow system. In the feed, the methyl bromide concentration is $0\mathrm{.}5641M$ and

the potassium iodide concentration is $0\mathrm{.}8329M.$ Calculate the concentration of species when the conversion is

$75\%.$
