Chapter 6, Problem 98CP

(a)

Interpretation Introduction

InterpretationWhether mole percent of ${\text{N}}_2{\text{O}}_5$ decomposed will be more than or less than or equal to $0.5\%$ should be explained.

Concept introduction: Chemical equilibrium is taken into consideration if rate of forward and backward reactions become equal. At this stage, both reactants and products have constant concentration. It can be studied in terms of pressure also. Equilibrium constant in pressure is denoted by $K_{\text{p}}$ .

(b)

Interpretation Introduction

Interpretation:Mole percentage of ${\text{N}}_2{\text{O}}_5$ decomposed for indicated reaction when volume isincreased by a factor of 10.0 is to be calculated.

  ${\text{2N}}_2{\text{O}}_5\left(g\right)\rightleftharpoons 4{\text{NO}}_2\left(g\right)+{\text{O}}_{\text{2}}\left(g\right)$

Concept introduction:The formula to evaluate molarity is given as follows:

  $M=\frac{n}{V}$

Where,

• $V$ represents volume.
• $M$ represents molarity.
• $n$ represents number of moles.
