1Z. Hydrolysis of methyl acetate in an alkaline medium
CH3 COOCH3 + OH- → CH3COO- + CH3OH
proceeds as a second-order reaction with a rate constant k = 0.137 mol-1*dm3*s-1 at 25°C. How long will it take for half of the starting substance to react if the initial concentrations of the components were 0.50 M? How long does it take for the starting substance to be used up almost completely (by 99%)?
