A mixture of propane and twice as much ethane are sent to a reactor with pure oxygen. A competing reaction occurs, so in addition to carbon dioxide and water, carbon monoxide is also produced. The conversion of propane is 100% while the conversion of ethane is 80% with 28 moles of CO₂
created. The selectivity (mole of CO₂/ mole of CO) is 4. If there is no remaining oxygen in the product stream, determine the following. [Don't assume a basis.]

a) Draw a flowchart.

b) Determine the number of moles of propane and ethane fed.

c) Determine the number of moles of oxygen fed.
