Chapter 9, Problem 30A

Interpretation Introduction

Interpretation: The limiting reactant for a process and its role to control the reaction needs to be explained.

Concept Introduction: A chemical reaction involves the conversion of reactant to product by breaking and making of chemical bonds.

There can be more than one reactant molecules involve in a chemical reaction to form the products. The product molecules exhibit different chemical and physical properties than reactant molecules.

Answer to Problem 30A

The reactant which is present in limited amount in a chemical reaction is called as limiting reactant. After complete consumption of limiting reagent, another reactant cannot form product so limiting reagent can limited the formation of product.

Explanation of Solution

The reactant which is present in limited amount in a chemical reaction is called as limiting reactant.

In a chemical reaction, if the limiting reactant will consume completely, the reactant cannot form more product in the absence of it. Thus after complete consumption of limiting reagent, another reactant cannot form product so limiting reagent can limited the formation of product.

Conclusion

Limiting reactant can limit the formation of product.
