)compare the mass of pet you used in this experiment to the amount of terephthalic acid monomer you obtainedby answering the following questions.(a) approximate the mass of terephthalic acidone would obtain if the depolymerization proceeded to completion. b) based on your answerto part (a) and the amount of terephthalic acidyou actuallyobtained, would you consider the depolymerization of pet (using the protocol you employed) an efficient process? explain your rationaleand be sure to account for any impurities observed by 1hnmr. c)provide a suggestion on how you might modify this experimental procedure to further improve the efficiency of the pet depolymerization reaction.
