Awrite a mechanism for the reaction step below. use half-headed (fishhook) curved arrows to show electron reorganization. consider only a process that lies on the pathway to product formation. when drawing bond formation by pairing of single electrons, terminate the arrows in a hotspot located to one side of a reacting radical. this hotspot is not associated with any structural feature.

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.
