FAQs on Stoichiometry & Limiting Reagent Video Lecture - Chemistry Class 11 - NEET

1. What is stoichiometry?
Ans. Stoichiometry is a branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. It involves determining the amount of reactants needed to produce a certain amount of product or vice versa.
2. What is a limiting reagent?
Ans. A limiting reagent is the reactant that is completely consumed in a chemical reaction, thereby limiting the amount of product that can be formed. It is the reactant that is present in the smallest stoichiometric amount and determines the maximum amount of product that can be obtained.
3. How is stoichiometry used in real-world applications?
Ans. Stoichiometry is used in various real-world applications, such as in the pharmaceutical industry to ensure the correct dosage of medications, in environmental science to calculate the amounts of pollutants released into the atmosphere, and in food production to determine the optimal ratios of ingredients for a recipe.
4. How can one determine the limiting reagent in a chemical reaction?
Ans. To determine the limiting reagent, one must compare the stoichiometric ratios of the reactants to the actual amounts of reactants present in the reaction. The reactant that has a smaller stoichiometric ratio compared to the others is the limiting reagent.
5. What are the consequences of not considering the limiting reagent in a chemical reaction?
Ans. Neglecting the limiting reagent in a chemical reaction can lead to incorrect predictions of the amount of product formed. It can result in wastage of reactants, as the excess reactants will not contribute to additional product formation. Additionally, it can affect the purity and yield of the desired product, leading to inefficient use of resources.
