For the 13C NMR data, assign the various resonances to the carbon nuclei responsible for them. Does the number of resonances observed in the 13C NMR spectrum allow you to prove that the cis- rather than the transdicarboxylic acid was produced by the hydrolysis of anhydride 6? Explain.

Which statement is actually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.
