Steam reforming of methane ( ) 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 tank with of methane gas and of water vapor at . he then raises the temperature, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be . calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to significant digits.
