Chapter 16, Problem 52AE

Interpretation Introduction

Interpretation:

Moles of $\text{HI}$ from reaction mixture of ${\text{H}}_2$ and ${\text{I}}_2$ has to be determined.

Concept Introduction:

The reactant in a reaction that tells about amount of product formed in a reaction is termed as limiting reagent. It helps to determine the yield of reaction.

The quantity of species that gives relation between reactants and products is determined by the stoichiometry of a reaction. Suppose the general reaction,

  $\text{2A}+\text{B}\to 3\text{C}$

In the above reaction, two moles of $\text{A}$ reacts with one mole of $\text{B}$ to form three moles of $\text{C}$. Therefore, stoichiometric ratio of A and B is $2:2$, of A and C is $2:3$ and of B and C is $1:3$.
