1. A certain amount of methyl was hydrolysed in the presence of an excess of 0.05 mol dm^-3 hydrochloric acid at 250C. When 25 cm^3 aliquots of reaction mixture were removed and titrated with NaOH solution, the volume V of alkali required for neutralisation after time t were as follows. t/ min 0 21 V/ cm^3 24.4 25.8 Determine reaction order with substitution methods and graphical methods and calculate the rate constant and half time this reaction.
