Chapter 12, Problem 51A

Interpretation Introduction

Interpretation: To determine the significance of limiting reagents in a chemical reaction.

Concept Introduction: Chemical reactions, as opposed to physical form changes or nuclear reactions, require the rearrangement of the molecular or ionic structure of a substance.

Answer to Problem 51A

In a chemical process, the reactant that would be consumed is the limiting reagent. The reaction cannot continue once that reactant is exhausted. As a result, it prevents the reaction from intensifying.

Explanation of Solution

A reactant that will be completely consumed at the end of a chemical reaction is known as the limiting reagent. This reagent controls the amount of product produced because the reaction would not be able to proceed without it.

Any additional reactants that are present in excess would then not be used up by one reactant.
