Limiting and Excess Reactants Is there enough of each chemical reactant to make a desired amount of product? Why? If a factory runs out of tires while manufacturing cars, production stops. No more ... cars can be fully built without ordering more tires. A similar thing happens in a chemical reaction. If there are fixed amounts of reactants to work with in a chemical reaction, one of the reactants may be used up first. This prevents the production of more products. In this activity, you will look at several situations where the process or reaction is stopped because one of the required components has been used up. Model 1 – Assembling a Race Car 1. How many of each part are needed to construct 1 complete race car? 4C 4P Body (B) Cylinder (Cy) Engine (E) Tire (Tr) 1 3 1 4 2.
