Acetaldehyde $($CH$3$CHO$)$ is produced by the dehydrogenation of ethanol:

C$2$H$5$OH $->$ CH$3$CHO $+$ H$2$

An undesired side reaction also occurs and produces ethyl acetate:

$2$C$2$H$5$OH $->$ CH$3$COOC$2$H$5+2$H$2$

In a pilot plant reactor, $90\%$ of the ethanol fed to the reactor is converted to products, and there is a $65\%$ yield of acetaldehyde $($based on the total amount of ethanol fed to the reactor$).$

Ethanol vapor enters the reactor at $300$oC$,5$ bar, and $100$ mol$/$hr$.$

We want to know how much heat to add or remove in order to keep the outlet temperature at $300$oC$.$
