Reactants Products Before reaction 3 mol N, O mol NH, 6 mol H, O mol H, After reaction 1 1 mol N, 4 mol NH, Reaction In presence of limiting reagent Ammonia, NHa, is created from the reactants N2 (shown in green) and H2 (shown in white) according to the following balanced chemical equation. In the example above you begin with 3 mol of nitrogen gas and 6 mol of hydrogen gas. N2 + 3H2 ----> 2NH3 Which is the limiting reactant? You can tell that nitrogen gas is the limiting reactant because there were fewer moles of it with which to begin. You can tell that ammonium is the limiting reactant because there were O moles of it before the reaction started. You can tell that hydrogen is the limiting reactant because all of it was used up, but there is some leftover (excess) nitrogen in the diagram when the reaction is complete Since the mole ratios match up perfectly between the reactants neither of them is limiting.

Chem 1101: Elements of Chemistry equation are the molar ratios for the reaction. For example, because 3 mol of Ba(NO3)2 react with 2 mol of Na3PO4, the molar ratio of Ba(NO3)2 to Na³PO4 is 3:2. I When the reactants are not present in the exact stoichiometric amounts required by the balanced equation, one reactant is in excess, and the other reactant is completely consumed. The maximum amount of product that can form is determined by the amount of reactant that is completely consumed, the limiting reactant. Using the previous example; if 6 mol of Ba(NO3)2 reacts with 8 mol of Na3PO4, how many mol of Ba3(PO4)2 forms. To answer this question the amount of Ba3(PO4)2 produced must be calculated from each reactant. 6 mol Ba(NO3)2,1 mol Ba, (PO4)₂2 3 mol Ba(NO3)₂ 1 8 mol Na3PO4 1 ·X 1 mol Ba, (PO4)2 2 mol Na3PO4 = 2 mol Ba, (PO4)₂ -= 4 mol Ba, (PO4)2 Experiment 11 Deta Since Ba(NO3)2 produces the smaller amount of product, it is totally consumed in the reaction and is called the limiting…
