Bimolecular and of second order

(B) The reaction involves two reactant molecules in the rate-determining step,so it is bimolecular.From the rate law $\frac{dx}{dt} = k[CH_3COOC_2H_5][NaOH]$,the sum of the powers of the concentration terms is $1 + 1 = 2$.Therefore,the reaction is of second order.Thus,the correct option is $B$.

The alkaline hydrolysis of ethyl acetate is represented by the equation $CH_3COOC_2H_5 + NaOH \to CH_3COONa + C_2H_5OH$. Experimentally,it is found that for this reaction $\frac{dx}{dt} = k[CH_3COOC_2H_5][NaOH]$. Then the reaction is

A
Bimolecular and of first order
B
Bimolecular and of second order
C
Pseudo-bimolecular
D
Pseudo-unimolecular
