P4.36 100 gmol/min of a solution of 70 mol % ethanol/30 mol % water is fed to a

reactor operating at steady state, along with 80 gmol/min of air (79 mol %

N₂, 21 mol % O₂). Ethanol (C₂H5OH) reacts with oxygen to make

acetaldehyde (CH,CHO). Acetaldehyde is further oxidized to acetic acid

(CH₂COOH). Write the two stoichiometrically balanced chemical

equations. What is the byproduct of the reactions? What is the limiting

reactant? If there is 100% conversion of the limiting reactant and the

production rate of acetaldehyde is 25 gmol/min, calculate the fractional

conversion of the excess reactant, the yield of acetaldehyde from ethanol,

and the composition and flow rate of the reactor effluent stream.
