During studies of the reaction below, 2 N2H4(l) + N2O4(l) ? 3 N2(g) + 4 H2O(g) a chemical engineer measured a less-than-expected yield of N2 and discovered that the following side reaction occurs. N2H4(l) + 2 N2O4(l) ? 6 NO(g) + 2 H2O(g) In one experiment, 10.2 g of NO formed when 111.4 g of each reactant was used. What is the highest percent yield of N2 that can be expected?
