SC Score: 0 of 1 point Incorrect Your answer is wrong. In addition to checking your math, check that you used the right data and DID NOT round any intermediate calculations. 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 75.0 L tank with 14. mol of methane gas and 5.8 mol of water vapor, and when the mixture has come to equilibrium measures the amount of carbon monoxide gas to be 2.3 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significant digits.
