A reactor uses $2$ chemicals A and B to form a desired product C$,$ and

undesired product D$.$

Assume the outlet stream has a mass flowrate of $100$ kg$/$hr$.$

Calculate the $\%$ conversion of A$,$ the yield of C and the $\%$ excess of B$.$

A$+$ B $2$C

A$+2$B $$ D

Species Mw

A $24$

B $18$

C $21$

D $60$

i$)$ Convert the outlet stream to moles.

ii$)$ Use the extent of reaction method to solve for the inlet molar

flowrates of A and B$.$

iii$)$ Calculate the $\%$ conversion of A

iv$)$ Calculate the $\%$ yield of C

v$)$ Calculate the $\%$ excess of B

$($c$)$

Calculate the heat of formation for the following balanced equation using the

table provided in the lecture notes.

CH$4($g$)+2$ O$2($g$)->$ CO$2($g$)+2$ H$2$O $($l$)$

$($d$)$

A reaction at $57$C has a rate constant of $0\mathrm{.}50$s$-1$ and activation energy of

$25$kJmol$-1.$ The temperature is increased to $127$C and the reaction reset.

What is the new rate constant at this higher temperature? $($Assume A

$($activation energy$)$ and concentrations are unchanged$)$
