Benzaldehyde is produced from toluene in the catalytic reaction

C$6$H$5$CH$3+$ O$2$ C$6$H$5$CHO $+$ H$2$O

C$6$H$5$CH$3+9$O$27$CO$2+4$H$2$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 CO$2$ and H$2$O$.$ The product gas

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

the product gases. Assume complete condensation.

IIa. Draw and label a complete flow chart for the process

IIb. Perform a degree of freedom analysis around the process.

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