Steam reforming methane (CH 4 ) produces synthesis a mixture of carbon monoxide and hydrogen gas, which the starting point for many important chemical syntheses. An chemist studying this reaction a tank 9.8 mol of methane gas and mol of water vapor and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 2.7 mol Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture.
