activation energy of hydrolysis of ethyl acetate
Answer: c Explanation: The equilibrium position of ethyl acetate hydrolysis was demonstrated to be temperature independent.
Because the bonds broken and created are of the same kind, calculating the heat of reaction using the bond energies technique yields a value of zero.
What is the rate of hydrolysis of ethyl acetate?
Conclusion: In conclusion, it can be seen from this experiment that rate of reaction is concentration dependent while rate constant is not.
Also, that the rate constant for the hydrolysis of ethyl acetate with sodium hydroxide using HCl as a catalyst at 28oC is approximately 0.003min-1cm-3.
What is the activation energy of saponification of ethyl acetate?
In their study, they used 0.
8) M ethyl acetate and 1.
0) M NaOH and conducted the experiments at five different temperatures ranging form 30 to 70°C.
They obtained the value of activation energy, 46.5 kJ mole−1, which was about 10% higher than the present value.
What is the reaction of the hydrolysis of ethyl acetate ester?
(C) Pseudo first order reaction.
