Chapter 3, Problem 3.41P

(a)

Interpretation Introduction

Interpretation: The limiting reactant amongst ${\text{A}}_{\text{2}}$ and ${\text{B}}_{\text{2}}$ should be identified.

Concept introduction:For some stoichiometric balanced equation; the reactant that is present in the smallest amount is consumed completely to form the product and thus governs the product formation.This reactant is known as limiting reactant.

Prior to the identification of the limiting reactant; a balanced equation is written, then the amount of each reactant in grams is converted to corresponding moles. Further on the basis of the stoichiometric molar ratio by which reactants combine, the amount of product formed from each of the reactants is calculated.

(b)

Interpretation Introduction

Interpretation:Number of product molecules ${\text{AB}}_3$ that can be formed should be calculated.
