A batch combustion chamber is loaded with 250 moles of ethene (C2H4) and 3000 moles of air (21.0 mol% of O2). The ethene combusts to form only carbon dioxide and water, but some ethene may remain unburned. At interruption the reactor contains 60 moles of O2. a) Enter the correct stoichiometric coefficients b) Which reactant is limiting? c) What is the extent of reaction at interruption? d) How many moles of each species are present at interruption?
