Limiting A Chemical ReactionTask: Watch The Video Introduction To Limiting Reactant And Excess Reactant. As You Watch, Answer The Following Question:In The Cooking Analogy Presented In The Video, Which Ingredient Is The Limiting Reactant: Bun,
What is a Limiting Reactant?
A limiting reactant is a substance that determines the amount of product formed in a chemical reaction. It is the reactant that is consumed first, and its availability limits the amount of product that can be formed. In other words, the limiting reactant is the reactant that is present in the smallest amount relative to the other reactants.
The Cooking Analogy
In the cooking analogy presented in the video, the ingredients are compared to reactants in a chemical reaction. The video explains that just as a recipe requires a specific amount of each ingredient to produce a certain amount of product, a chemical reaction requires a specific amount of each reactant to produce a certain amount of product.
Which Ingredient is the Limiting Reactant?
In the cooking analogy, the bun is the limiting reactant. This is because the bun is the ingredient that is present in the smallest amount relative to the other ingredients. If you have a certain amount of meat, cheese, and sauce, but only one bun, the bun will be the limiting reactant, and the amount of product (in this case, the sandwich) that can be formed will be limited by the availability of the bun.
Why is the Bun the Limiting Reactant?
The bun is the limiting reactant because it is the ingredient that is present in the smallest amount relative to the other ingredients. If you have a certain amount of meat, cheese, and sauce, but only one bun, the bun will be the limiting reactant, and the amount of product (in this case, the sandwich) that can be formed will be limited by the availability of the bun.
How to Identify the Limiting Reactant
To identify the limiting reactant, you need to compare the mole ratio of the reactants to the mole ratio of the products. The reactant that is present in the smallest amount relative to the other reactants is the limiting reactant.
Example:
Suppose you have a chemical reaction that requires 2 moles of A and 3 moles of B to produce 4 moles of C. If you have 2 moles of A and 4 moles of B, which reactant is the limiting reactant?
To answer this question, you need to compare the mole ratio of the reactants to the mole ratio of the products. The mole ratio of the reactants is 2:4, and the mole ratio of the products is 4:1. Since the mole ratio of the reactants is not equal to the mole ratio of the products, the limiting reactant is the reactant that is present in the smallest amount relative to the other reactants.
In this case, the limiting reactant is B, because it is present in the smallest amount relative to the other reactants.
Conclusion
In conclusion, the limiting reactant is the substance that determines the amount of product formed in a chemical reaction. It is the reactant that is consumed first, and its availability limits the amount of product that can be formed. To identify the limiting reactant, you need to compare the mole ratio of the reactants to the mole ratio of the products. The reactant that is present in the smallest amount relative to the other reactants is the limiting reactant.
