Benzaldehyde is produced from toluene in the catalytic reaction

$C_6{H}_{5}C{H}_3+O_2{C}_6{H}_5$CHO$+H_{2}O$

$C_6{H}_{5}C{H}_3+9O_{2}7C{O}_2+4H_{2}O$

Dry air and toluene enter the reactor. Air is supplied in $100\%$ excess. Of the toluene fed to the reactor,

$13\%$ reacts to form benzaldehyde and $0\mathrm{.}5\%$ reacts with $O_2$ to produce $C{O}_2$ and $H_{2}O.$ The product gas

leaves the reactor and enters a condenser. Over a four hour period, $13\mathrm{.}1kg$ of water is condensed from

the product gases. Assume complete condensation.

I Draw and label a complete flow chart for the process

II Perform a degree of freedom analysis around the process.

IlI Calculate the molar flow rates of toluene into the process and of benzaldehyde in the product.
