With a particular catalyst and at a given temperature, the oxidation of naphthalene to phthalic anhydride proceeds as follows:

What reactor type gives the maximum yield of phthalic anhydride? Roughly estimate this yield and the fractional conversion of naphthalene which will give this yield. Note the word "roughly".
