Dec 24, 2014 · Solving Limiting Reactant Problems In the real world, amounts of reactants and products are typically measured by mass or by volume. It is first necessary to convert the given quantities of each reactant to moles in order to identify the limiting reactant. Sample Problem 12.9: Determining the Limiting Reactant That is, that after all the oxygen has been consumed, 5 moles of hydrogen left over. The O2 is the limiting reactant One way to solve the problem of what is the limiting reagent is: Calculate the amount of product to be formed for each of the quantities to the reaction reagent. The limiting reactant is one that produces the least amount of product. In fact, the best mixture consists of exactly as much reagent A as reagent B that would allow for no reactants to be left over. Finding the Limiting Reagent . For practice, let’s look at the following example and see if we can determine which reagent is limiting and which is in excess. Limiting Reagent Worksheet All of the questions on this worksheet involve the following reaction: When copper (II) chloride reacts with sodium nitrate, copper (II) nitrate and sodium chloride are formed.
