WebApr 23, 2014 · It "limits" the reaction. All other reactants are in "excess". When calculating how much product can be made, always start calculations with the limiting reagent because it determines how much product can be made. This is an analogy which helped me: Suppose we are making sandwiches. WebThe reactant that is completely consumed is the limiting reactant, and the reactant present in a quantity greater than necessary to react completely with the limiting reactant is the excess reactant. A recipe analogy is helpful to understand these concepts. Here, one cup of flour, 2 eggs, and 3 tablespoons of sugar make five waffles. If there ...
