At 298 K, the equilibrium concentration of O2 is 1.6 x 10-2 M, and the equilibrium concentration of O3 is 2.86 x 10-28 M. What is the equilibrium constant of the reaction at this temperature?

Answer :

Answer:

The equilibrium constant of the reaction at this temperature is [tex]2.147 \times 10^{-50}[/tex]

Explanation:

Equilibrium is the condition at which the reactants and products concentration is constant.

At equilibrium rate of the forward reaction = rate of the backward or reverse reaction  

The Chemical equilibrium is  

[tex]3O_2   <--->2O_3[/tex]

[tex]K_c[/tex] is the equilibrium constant and is defined as products concentration over reactant concentration and the coefficient is raised to its power. Thus we have the [tex]K_c[/tex] expressed as

[tex]K_c = \frac {[Products concentration]}{[Reactants concentration]}[/tex]

Plugging in the values given in the question, we have

[tex]K_c =\frac {[O_3 ]^2}{[O_2 ]^3}[/tex]

[tex]=\frac {((2.86\times10^{-28})^2)}{(1.6\times10^{-2})^3}[/tex]

[tex]=\frac {(8.1796\times10^{-56})}{(4.096\times10^{-6})}[/tex]

[tex]=2.147 \times 10^{-50}[/tex] (Answer)
