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. Show that it follows a pseudo first order reaction, as the concentration of water remains nearly constant (55 mol L^(-1)), during the course of the reaction. What is the value of k in this equation? Rate = k [CH_3C00CH_3][H_20]

Direction. In the following questions, a statement of assertion is followed by a statement of reason. While answering a question, you are required to choose the correct are out of the given four responses and mark it as (A)If both assertion and reason are true and reason is the correct explanation of the assertion, (B) if both assertion and reason are true but reason is not correct explanation of the assertion. (C) if assertion is true, but reason if false, (D) if both assertion and reason are false Assertion : If delta_1 and delta_2 are the angle of dip observed in two planes at right angles to eah other, then the true angle of dip. delta = (delta_1 + delta_2)/2 Reason : It is not possible to determine the true angle of dip from the given observed values
