Understanding the Reaction
The acid-catalyzed hydrolysis of ethyl acetate is an important reaction in organic chemistry. It can be represented as follows:
- Ethyl acetate (an ester) reacts with water in the presence of an acid catalyst to produce ethanol and acetic acid.
- The reaction typically follows pseudo-first-order kinetics when one reactant is in excess.
Pseudo-First Order Kinetics
- In a pseudo-first-order reaction, the concentration of one reactant (in this case, water) is much higher than the other reactant (ethyl acetate).
- This allows the rate to depend primarily on the concentration of the ester while treating the concentration of water as constant.
Excess of Ester
- When the reaction is carried out with a large excess of ethyl acetate, the concentration of the ester remains significantly higher than that of the water.
- Thus, any change in the concentration of the ester will not affect the overall reaction rate significantly.
Determining the Order
- The overall order of the reaction is determined by how the rate changes with varying concentrations of the reactants.
- With the ester in excess, the reaction behaves as if it is zero-order with respect to that reactant because its concentration does not change appreciably during the reaction.
Conclusion
- Therefore, the order with respect to ethyl acetate (the ester) in this scenario is effectively 0.
- This aligns with the provided correct answer option 'B', confirming that under these conditions, the reaction exhibits zero-order kinetics concerning the ester.
