Chapter 17, Problem 17.98P

(a)

Interpretation Introduction

Interpretation:

Overall equation for the reaction of propane and steam to produce steam and carbon dioxide has to be written.

(b)

Interpretation Introduction

Interpretation:

${\text{K}}_{\text{P}}$ for the overall process has to be calculated.

Concept Introduction:

Equilibrium constant using partial pressure:

The equilibrium constant of partial pressure can be defined as the ratio of products and reactants concentration at equilibrium in terms of partial pressure.

For a reaction,

  ${\text{aA}}_{\text{(g)}}{\text{+ bB}}_{\text{(g)}}\rightleftharpoons {\text{cC}}_{\text{(g)}}{\text{+ dD}}_{\text{(g)}}$

The expression of ${\text{K}}_{\text{p}}$ can be given as

  ${\text{K}}_{\text{p}}\text{ = }\frac{{{\text{(P}}_{\text{C}}\text{)}}^{\text{c}}{{\text{(P}}_{\text{D}}\text{)}}^{\text{d}}}{{{\text{(P}}_{\text{A}}\text{)}}^{\text{a}}{{\text{(P}}_{\text{B}}\text{)}}^{\text{b}}}$

(c)

Interpretation Introduction

Interpretation:

The final pressure has to be found, when 1.00 volume of ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}$ and 4.00 volumes of ${\text{H}}_{\text{2}}\text{O}$, each at 1200.K and 5.0atm, are mixed in a container.

Concept Introduction:

Equilibrium constant using partial pressure:

The equilibrium constant of partial pressure can be defined as the ratio of products and reactants concentration at equilibrium in terms of partial pressure.

For a reaction,

  ${\text{aA}}_{\text{(g)}}{\text{+ bB}}_{\text{(g)}}\rightleftharpoons {\text{cC}}_{\text{(g)}}{\text{+ dD}}_{\text{(g)}}$

The expression of ${\text{K}}_{\text{p}}$ can be given as

  ${\text{K}}_{\text{p}}\text{ = }\frac{{{\text{(P}}_{\text{C}}\text{)}}^{\text{c}}{{\text{(P}}_{\text{D}}\text{)}}^{\text{d}}}{{{\text{(P}}_{\text{A}}\text{)}}^{\text{a}}{{\text{(P}}_{\text{B}}\text{)}}^{\text{b}}}$

(d)

Interpretation Introduction

Interpretation:

The percentage of ${\text{C}}_{\text{3}}{\text{H}}_{\text{8}}$ unreacted has to be determined.
