Nitric acid (NO) reacts with oxygen gas to form nitrogen dioxide (NO2), a dark brown gas:
2NO(g) + O2(g) → 2NO2(g)
In one experiment 0.886 mole of NO is mixed with 0.503 mol of O2.
Calculate which of the two reactants is the limiting reagent.
Calculate also the number of moles of NO2 produced.
What reactant is left over and how much of it is left over?
