Suppose that an atmospheric chemist combines 165 of methane at STP, 870 of oxygen at STP, and 56.5 of at STP in a 1.8 flask. The reaction is allowed to stand for several weeks at 275 .If the reaction reaches 90.0% of completion (90.0% of the limiting reactant is consumed), what are the partial pressures of each of the reactants in the flask at 275 ?
