Answer: The final concentration of at equilibrium is 0.36 M
Explanation:
Moles of = 0.64 mole
Volume of solution = 1.0 L
Initial concentration of =
The given balanced equilibrium reaction is,
Initial conc. 0.64 M 0M 0M
At eqm. conc. (0.64-x) M (x) M (x) M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get
By solving the term 'x', we get :
x = 0.36
Thus, the final concentration of at equilibrium is x = 0.36 M

Explanation:
The Fischer esterification reaction is a nucleophilic substitution <u>in the acyl group of a carboxylic acid, catalyzed by an acid.</u>
1) The protonation of the oxygen of the carbonyl group activates the carboxylic acid...
2) ... against a nucleophilic attack by the alcohol, and produces a tetrahedral intermediate.
3) The transference of a proton from an oxygen atom to another produces a second tetrahedral intermediate and converts the -OH into a good leaving group.
4) The loss of a proton and the expulsion of H₂O regenerates the acid catalyzer and gives an ester as a product.
