The kinetic of hydrolysis of methyl acetate in excess dilute HCl at 25°C were followed by withdrawing 2 mL of the reaction mixture at intervals of (t), adding 50 mL water and titrating with baryta water. Determine the velocity constant of hydrolysis.
t (in minute) 0 75 119 259 ∞
Titre value (in mL) 19.24 24.20 26.60 32.23 42.03
[ln 
= 0.2454, ln 
= 0.39, ln 
= 0.8439]
