Chapter 9.2, Problem 9.5QAP

Interpretation Introduction

(a)

Interpretation:

To write mole-mole factors relationship between moles of SO₃ from the moles of SO₂ for the following reaction:

  ${\text{2SO}}_{\text{2}}\text{(g)}\text{+}{\text{O}}_{\text{2}}\text{(g)}\to {\text{2SO}}_{\text{3}}\text{(g)}$

Concept Introduction:

A stoichiometric coefficient of a well balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.

Lets say we have a chemical reaction as:

  $\text{aA}\text{+bB}\to \text{cC}\text{+}\text{dD}$

If above reaction is well-balanced then,

'a' moles of A reacts with b moles of B to produce c moles of C and d moles of D.

Interpretation Introduction

(a)

Interpretation:

To write the mole-mole factor relationship for the moles of O₂ needed to react with P for the given reaction:

  $\text{4P}\text{(s)}\text{+}5{\text{O}}_{\text{2}}\text{(g)}\to 2{\text{P}}_{\text{2}}{\text{O}}_5\text{(s)}$
