Chapter F, Problem M.6E

(a)

Interpretation Introduction

Interpretation:

Excess reactant has to be identified if the reaction is carried out using $\text{12}\text{mol}{\text{N}}_{\text{2}}{\text{H}}_{\text{4}}$ and $\text{12}\text{mol}{\text{ClF}}_{\text{3}}$.

Concept Introduction:

In a chemical reaction, the limiting reactant is the one that is present in lesser quantity than the required stoichiometric ratio between the various reactants that is present in it.  This limiting reactant decides the maximum yield of the product that will be formed in a chemical reaction.

(b)

Interpretation Introduction

Interpretation:

The moles of each product that will be formed and the moles of reactant that will be present in excess has to be estimated.
