Ethyl ethanoate undergoes following reaction [on the picture]

Equal amounts of ethanoic acid and ethanol were mixed together and allowed to reach equilibrium.

At equilibrium, the concentrations of both ethanoic acid and ethanol were 0.42 mol dm^-3.

What is the concentration of ethyl ethanoate at equilibrium?

Sagot :

Answer: The concentration of ethyl ethanoate at equilibrium is [tex]0.653mol/dm^3[/tex]

Explanation:

Given values:

Equilibrium concentration of ethanol = [tex]0.42mol/dm^3[/tex]

Equilibrium concentration of ethanoic acid = [tex]0.42mol/dm^3[/tex]

[tex]K_c=0.27[/tex]

The given chemical equation follows:

[tex]CH_3COOC_2H_5+H_2O\rightleftharpoons C_2H_5OH+CH_3COOH[/tex]

The expression of [tex]K_c[/tex] for above equation follows:

[tex]K_c=\frac{[C_2H_5OH][CH_3COOH]}{[CH_3COOC_2H_5]}[/tex]

Putting values in above expression, we get:

[tex]0.27=\frac{0.42\times 0.42}{[CH_3COOC_2H_5]}[/tex]

[tex][CH_3COOC_2H_5]=\frac{0.42\times 0.42}{0.27}=0.653mol/dm^3[/tex]

Hence, the concentration of ethyl ethanoate at equilibrium is [tex]0.653mol/dm^3[/tex]
