Question

Acrylic acid (CH2 CHCOOH) is used to prepare polymers, adhesives, and paints. The first step in making acrylic acid involves the vapor-phase oxidation of propylene (CH2 CHCH3) to acrolein (CH2 CHCHO). This step is carried out at 377.7°C and 4.7 atm in a large bundle of tubes around which a heat transfer agent circulates. The reactants spend an average of 1.4 s in the tubes, which have a void space of 175.2 ft3. How many mols of propylene must be added per hour in a mixture whose mole fractions are 0.07 propylene, 0.35 steam, and 0.58 air?
