Which of the following statements is correct?

Alkaline hydrolysis of an ester is a reversible reaction.

In the alkaline hydrolysis of an ester, the bond broken is the bond between oxygen and alkyl group.

Alkaline hydrolysis of an ester follows second order kinetics and is thus ${\mathrm{S}}_{\mathrm{N}}2$.

An electron-withdrawing group G in $p-{\mathrm{GC}}_6{\mathrm{H}}_4{\mathrm{COOC}}_2{\mathrm{H}}_5$ decreases the rate of hydrolysis as compared to ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{COOC}}_2{\mathrm{H}}_5$.
