However, the reactants for a reaction in an experiment are not necessarily a stoichiometric mixture.Limiting reagentThe limiting reagent in a reaction is the first to be completely used up and prevents any further reaction from occurring. In this reaction, reactant B is the limiting reagent because there is still some left over A in the products. Therefore, A was in excess when B was all used up. Determining the Limiting ReagentThe theoretical yield is the maximum amount of product that would be produced through the complete consumption of the limiting reagent. Excess Reagent: The quantity (mole or mass) left over after the complete consumption of the limiting reagent. Quantity Excess = Initial Quantity - Consumed Quantity. Where quantity can be moles or mass.
