Answer:
B
pseudo first order
A reaction which is not the first-order reaction naturally but made the first order by increasing or decreasing the concentration of one or the other reactant is known as Pseudo first-order reaction.
Hydrolysis of ethyl acetate in presence of an excess of water:
CH 3 COOC2H5+H2O(excess)H+CH3 COOH+C2 H 5OH
r=k[CH 3COOC 2 H5 ]2 [H2O] 0
Excess [H 2O] can cause the independency of reaction on H 2O.
Hence, it is a pseudo-first-order reaction.
Hence, the correct answer is option B
