ชุดทดลองอัตราการเกิดปฏิกิริยาและพลังงานกระตุ้นของกรดไฮโดรไลซิสของเอทิลอะซีเตต

Principle

In acid solution, ethyl acetate is hydrolysed to equivalent quantities of ethanol and acetic acid according to a pseudo-first order rate law. The alkalimetric determination of the acetic acid formed enables conclusions to be drawn on the temporal concentration of ester.

Benefits

• Thermostat for precise temperature control
• Stable and safe construction due to solid stand material

Tasks

1. Determine the reaction rate constant for the acidolysis of ethyl acetate at two (or more) temperatures.
2. Calculate the activation energy of the reaction from the temperature dependence of the measured rate constants.

Learning objectives

1. Reaction rate
2. Reaction rate constant
3. Rate law for first and second order reactions
4. Reactions with pseudo order
5. Arrhenius equation
6. Activation energy
