A batch combustion chamber is loaded with 151 moles of methane and 909 moles of air (21.0mol% O2 ). The methane combusts to form only carbon dioxide and water, but some methane may remain unburned. At interruption, the reactor contains 59.69 moles of O2. a) Enter the correct stoichiometric coefficients. CH4+O2_CO2+H2O 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
