Solution

Solution Steps

Step 1: Understanding Yield in Chemical Reactions

In a chemical reaction, the yield refers to the amount of product formed. There are two types of yields: theoretical yield and actual yield. The theoretical yield is the maximum amount of product that can be formed from the given amounts of reactants, assuming complete conversion with no losses. The actual yield is the amount of product actually obtained from the reaction.

Step 2: Identifying Limiting and Excess Reactants

In a chemical reaction, the limiting reactant is the reactant that is completely consumed first, limiting the amount of product that can be formed. The excess reactant is the reactant that remains after the reaction has gone to completion.

Step 3: Relationship Between Reactants and Yield

The theoretical yield is calculated based on the amount of the limiting reactant because it determines the maximum amount of product that can be formed. The actual yield is not directly calculated from the reactants but is measured from the experiment.
