Question

a. Calculate the total molar amount and mole fractions of methanol, air (N2+O2)
and water fed to the reactor.
b. Determine the extents of reaction, ??̇1and ??̇2.
c. Calculate the fractional conversion of methanol. 

2. Formaldehyde (CH₂O) is made by the catalytic oxidation of methanol vapor and humid air in
a reactor. The fed air humidity is unknown. The molar output from this batch reactor are 63.1
mol N2, an unknown amount of O2, 25.9 mol H₂O, 17.2 mol of CH₂O, 12.3 mol CH3OH, and
1.2 mol HCOOH. The reaction is:
CH3OH +0₂ → CH₂O + H₂O
(1)
A side reaction is occurring:
CH,O +}0 → HCOOH
(2)
