Chemistry

100 moles/hour of pure ethane at 25 degrees Celsius and 1.0 atmare burned with 50.0% excess air producing a desired product ofcarbon dioxide and an undesired product of carbon monoxide. Thefractional conversion of the ethane is 80.0% (on a molar basis).95% of ethane that reacts goes to carbon dioxide. Determine themolar flow rate and molar composition of the gaseous productstream, which is at 400 degrees Celsius and 1.0 atm.

Completely label your diagram, list the temperature, pressure, flowrate, and composition (mole fractions with indexes) for eac stream,supply values and units for knowns and question marks forunknowns.

Chemical Reactions:
I: C2H6 + O2 ---> CO2 + H2O
II: C2H6 + O2 ---> _CO + _H2O
