The limiting reactant of a reaction is the reactant that would run out first if all the reactants were to be reacted together. Another way to put it is to say that O2 is in excess. When the reaction has proceeded to completion, all of the H2 will have been consumed, leaving some O2 and the product...

Limiting and Excess Reactants 1. Figure out which of the reactants is the limiting reactant or limiting reagent. 2. See how much product can be formed by using the maximum amount of the limiting reactant or limiting reagent. 3. The excess reactant is what is left over after all of the limiting reactant has been used up. Example: 1.

Dec 26, 2007 · So NO is the limiting reactant and oxygen is the excess reactant. To get the theoretical yield, just calculate how much product would be created at the point where the limiting reactant is used up. In this case, the ratio of NO to NO2 is 1 to 1, so the moles of product formed would be equal to the moles of limiting reactant which is 4 moles ...
