An aqueous solution of ethyl acetate is to be saponified with sodium hydroxide.Initial conc. Of ethyl acetate is 5g/L and that of caustic is 0.1 M. The values ofsecond order rate constant at 0 oC and 20 oC are k = 0.235 and 0.924 (L/mol/min),respectively. The reaction is irreversible. Calculate the time required to saponify95% of ester at 40 oC.
