Methyl acetate reacts in acidic solution. h+ ch3cooch3 + h2o h ch3oh + ch3cooh methyl acetate methanol acetic acid the rate law is first order in methyl acetate in acidic solu- tion, and the rate constant at 25°c is 1.26 × 10−4/s. how long will it take for 65% of the methyl acetate to react?

Answer asap need to be answered by wednesday morning explain how a buffer works, using an ethanoic acid / sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
