Chapter 15, Problem 15.107SP

Interpretation Introduction

Interpretation:

The value of ${\text{k}}_{\text{1}}$ has to be determined using the given data.

Concept Introduction:

• Equilibrium constant: at equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K

  For a general reaction, $\text{aA+bB}\rightleftarrows \text{cC+dD}$

  $\text{Equilibrium}\text{constant}\text{K}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$

• Equilibrium constant can be expressed as the ratio of forward constant to the rate of backward rate constant for the reverse reaction.

  ${\text{K}}_{\text{c}}\text{=}\frac{{\text{k}}_{\text{f}}}{{\text{k}}_{\text{r}}}$
