|
Reaction rate and rate constant of the hydrolysis of ethyl acetate with
ethanol as the product from which second order rate constant can be calculated: CH3COOC2H5 + NaOH CH3COONa + C2H5OH Ethyl acetate sodium hydroxide sodium |
This reaction is a second order reaction because the rate of reaction is directly proportional to the both of the reactants.
This is called saponification of Ethyl acetate.
Formula used: \\[k = \\dfrac{1}{t}\\dfrac{{\\left( {{V_0} - {V_t}} \\right)}}{{{V_0}{V_t}}}\\]; k=rate constant for saponification of Ethyl acetate.
Why is hydrolysis of ethyl acetate pseudo first order?
As the [water] does not change significantly if it is in vast excess, the rate of reaction in this case is said to be 'pseudo first order' with respect to the [ethylacetate].
What is the order of hydrolysis of ester?
Assertion : Hydrolysis of ester in acidic medium follows first order kinetics Reason: Hydrolysis ofester is independent of the concentration of acid used.
CHEMISTRY.
What is the order of reaction of hydrolysis of ethyl acetate?
Assertion :Hydrolysis of ethyl acetate in presence of acid is a reaction of first order whereas in presence of alkali, it is a reaction of second order.
Reason: Acid acts as catalyst only whereas alkali acts as one of the reactant.
