Question
What determines the effect of a limiting reagent on the mass of a product?A.The amount of the limiting reagentB.The molar mass of the limiting reagentC.The reactivity of the limiting reagentD.The coefficient of the limiting reagent
Solution
The effect of a limiting reagent on the mass of a product is determined by:
A. The amount of the limiting reagent: This is the most direct factor. The limiting reagent is the substance that is completely consumed in a chemical reaction. Therefore, the amount of product formed is directly proportional to the amount of limiting reagent used.
B. The molar mass of the limiting reagent: This is also a significant factor. The molar mass of the reagent determines how much of it is needed to react with the other reagents. A reagent with a higher molar mass will produce more product than a reagent with a lower molar mass, assuming all other factors are equal.
C. The reactivity of the limiting reagent: This is not typically a factor that affects the mass of the product. The reactivity of a reagent refers to how readily it undergoes a chemical reaction, but it does not directly affect the mass of the product formed.
D. The coefficient of the limiting reagent: This is a factor in the sense that it determines the stoichiometry of the reaction, or the ratio in which the reagents react to form the product. However, it does not directly affect the mass of the product. Rather, it affects the amount of each reagent that is needed for the reaction to proceed.
