3.5 ml ethyl acetate was added to a flask containing 100 ml of 0.1 M HCI placed in a thermostat maintained at `30^(@)`C 5 ml of the reaction mixture was withdrawn at different interval of time and after chilling titrated against standard NaOH the following data were obtained
Time (minutes) 0 75 119 183 `infty`
NaOH used (mL) 9.62 12.10 13.10 14.75 21.05
From the above data show that the hydrolysis of ethyl acetate is a first order reaction

Here, `V_(oo) - V_(0) = 21.05 - 9.62 = 11.43 mL`

A constant value of k shows that hydrolysis of ethyl acetate is a first order reaction.
