Answer:
[CH₂CO₂C₂H₂(aq)] * [H₂O(l)] / [CH3CO₂H(aq)] * [C₂H₂OH(aq)]
Step by step explanation:
The concentration equilibrium constant expression, also known as the Keq, is written as the ratio of the products' concentrations to the reactants' concentrations, each raised to their stoichiometric coefficients. For the given reaction:
CH3CO₂H(aq) + C₂H₂OH(aq) → CH₂CO₂C₂H₂(aq) + H₂O(l)
The equilibrium constant expression can be written as:
Keq = [CH₂CO₂C₂H₂(aq)] * [H₂O(l)] / [CH3CO₂H(aq)] * [C₂H₂OH(aq)]
Here, the square brackets denote the concentrations of the respective species in the reaction. The coefficients in the balanced chemical equation are used as the exponents in the Keq expression.
