Look at the structures of the two possible aromatic esters proposed in the lab manual (methyl salicylate, methyl benzoate). While the experiment we did (hydrolysis to the acid followed by the mp determination) is a perfectly acceptable way to identify the unknown, identification could also have been done with spectroscopy. Recommend a spectroscopic technique and describe how you would use it to establish the correct structure.

Steam reforming of methane ( ch4) produces "synthesis gas," a mixture of carbon monoxide gas and hydrogen gas, which is the starting point for many important industrial chemical syntheses. an industrial chemist studying this reaction fills a 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.
