Steam reforming of methane ( CH, ) 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 50.0 L tank with 15. mol of methane gas and 4.1 mol of water va and when the mixture has come to equlibrium measures the amount of hydrogen gas to be 7.4 mol. Calculate the concentration equilibrium constant for the steam reforming of methane at the final temperature of the mixture. Round your answer to 2 significa digits. K-0

Question
Steam reforming of methane ( CH, ) 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 50.0 L tank with 15. mol of methane gas and 4.1 mol of water vapor,
and when the mixture has come to equlibrium measures the amount of hydrogen gas to be 7.4 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.
K-0
At -15.7 °C the pressure equilibrium constant K, =6.8 for a certain reaction.
Here are some facts about the reaction:
• The initial rate of the reaction is 6.0 mol·Ls.
• If the reaction is run at constant pressure, 81.0 kJ/mol of heat are released.
• If the reaction is run at constant pressure, the volume increases by 14.%.
O Yes.
Using these facts, can you calculate K, at 7.2 °C?
O No.
If you said yes, then enter your answer at right. Round it to
2 significant digits.
Yes, and K, will be
bigger.
If you said no, can you at least decide whether K, at
7,2 °C will be bigger or smaller than K, at -15.7 °C?
Yes, and K, will be
smaller.
O No.
