Methane and oxygen react in the presence of a catalyst to form formaldehyde. In a parallel reaction, methane is oxidized to carbon dioxide and water: CH_4 (g) + O_2 (g) rightarrow HCHO (g) + H_2O (g) (1) CH_4 (g) + 2O_2 (g) rightarrow CO_2 (g) + 2H_2O (g (2) The species recovered after the reaction takes place for some time are listed in Table 2. Product stream composition. Based on the product distribution in Table 2, assuming that the feed consisted only of CH_4 and O_2, calculate the following: 1. How much CH_4 and O_2 were fed to the reactor in gram moles? 2. What was the limiting reactant? 3. What was the excess reactant? 4. What was the fraction conversion of CH_4 to HCHO? 5. What was the selectivity of HCHO relative to CO_2? 6. What was the yield of HCHO expressed in grams of HCHO to the grams of CH_4 fed to the reactor? 7. What was the extent of reaction of Reactions (1) and (2)?
