The saponification of ethyl acetate with sodium hydroxide proceeds with second- order kinetics. At temperature 283 K the value of the rate constant was k₂ = 2.38 dm³mol-1min-1. After what time will 40% of the ester have saponified if 1 dm³ of a 100 mol/m³ ester solution was reacted with 1 dm³ of a 100 mol/m³ NaOH solution at 283 K?
