C2H5OH(l) + C2H5CHOOH(l) ⇌ C2H5COOC2H5(l) + H2O(l)

Is this a reactant or product favored at equilibrium?

To determine if this reaction is reactant or product favored at equilibrium, we need to examine the reaction's equilibrium constant (Keq) value.

The equilibrium constant (Keq) is calculated by dividing the concentration of the products by the concentration of the reactants, each raised to their stoichiometric coefficients:

Keq = [C2H5COOC2H5] / ([C2H5OH] * [C2H5CHOOH] * [H2O])

If the Keq value is greater than 1, it means that the concentration of the products is higher than the reactants, indicating that the reaction is product-favored at equilibrium. Conversely, if the Keq value is less than 1, it means that the concentration of the reactants is higher than the products, indicating that the reaction is reactant-favored at equilibrium.

Since we don't have specific concentration values for the species involved in the reaction, we cannot determine whether it is reactant or product favored at equilibrium based solely on the given equation. The Keq value would need to be determined experimentally or provided in order to make a definitive conclusion.
