## Step 1In a chemical reaction, the reactants are the substances that undergo a chemical change to form the products. The reactants are the starting materials in a chemical reaction.## Step 2The excess reagent is the reactant that is present in a larger amount than is required to react with the other reactants. This means that it is not completely consumed in the reaction.## Step 3The excess reagent does not control the reaction. The reaction is controlled by the limiting reagent, which is the reactant that is completely consumed in the reaction.## Step 4The excess reagent is not completely consumed in the reaction. This is because it is present in a larger amount than is required to react with the other reactants.## Step 5The excess reagent is present in a larger amount than the limiting reagent. This is because it is not completely consumed in the reaction, while the limiting reagent is completely consumed.
