Challenge 1 - Easy) CO2 conversion Pure CO2 is fed to the reactor at a known molar flowrate of nCO2,0 moles/s. A fraction of the CO2 will be converted to CO and O2, with the overall reaction given by: CO2CO+1/2O2 We are able to measure mole fraction (i.e. molar concentration) of CO and CO2 in the product stream. We cannot directly measure the total molar flowrate leaving the reactor, and we cannot measure O2. Write equations in terms of known variables for: a) The moles of CO2,CO, and O2 formed. b) The conversion of CO2 Finally, test your calculations - what CO2 conversion do you have if you have a CO2 fraction of 0.7 in the products? Hint - the answer isn't 30%; make sure you understand why. Challenge 2 - Medium) Nitrogen fixation Air is fed to the plasma reactor at a total flowrate nT,0mol/s. The percentage mole fraction of the feed can be assumed to be 80%N2 and 20%O2. Various gases are produced in the reactor - we can measure these: NO2NO2, and N2O. As before, we cannot measure N2 or O2. a) Write equations for the concentration of NO,NO2 and N2O in terms of known variables. b) Show that it is possible to determine N2 and O2 conversion without being able to measure their mole fraction in the product gas
