Hydrolysis of methyl acetate in aqueous solution has been studied by titrating the liberated acetic acid against sodium hydroxide. The concentration of the ester at different times is given below. {:("t(min)",0,30,60,90),(C("mol.L"^(-1)),0.8500,0.8004,0.7538,0.7096):} Show that it follows a pseudo first order reaction as, the concentration of water remain nearly constant (55"mol.L"^(-1)) , during the course of the reaction what is the value of k' in this equation ?
