1 mL of methyl acetate was added to a flash containing 20 mL of N/20 HCl maintained at `25@C`. 2mL of the reaction mixture were withdrawn at different intervals and titrate with a standard alkali solution. The following results were obtained :
`{:("Time (min)",0,75,119,183,oo),("Alkali used (mL)",19.24,24.20,26.60,29.32,42.03):}`
show that the reaction follows first order kinetics

Methyl acetate was subjected to hydrolyiss in N-HCl at 298 K . 5mL of the mixture is withdraw at different intervals and titrated with constant with about N//8NaOH . The following results were obtained: |{:("Time (min)",0,25,40,61,oo),("Vol of alkali used (mL)",19.24,24.20,26.60,29.32,42.03):}| Show that the reaction is of first order.
