Steam reforming of methane ( CHA) 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 34. mol of methane gas and 14. mol of water vapor, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 4.2 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.

5. Given PCl5 ---> PCl3 + Cl2. 0.23 mol of PCl5 is placed in a 2.00L container. At equilibrium, 0.15mol of PCl5 is found. Calculate Keq                        6. The synthesis of NH3 is given by N2 + 3H2 ---> 2NH3 all in the gas state. If the equilibrium constant is 2.73x10-8,what concentration of ammonia would be found if you began with 1.1M of each of the reactants?

Ammonia has been studied as an alternative "clean" fuel for internal combustion engines, since its reaction with oxygen produces only nitrogen and water vapor, and in the liquid form it is easily transported. An industrial chemist studying this reaction fills a 25.0 L tank with 5.3 mol of ammonia gas and 2.4 mol of oxygen gas, and when the mixture has come to equilibrium measures the amount of nitrogen gas to be 1.4 mol. Calculate the concentration equilibrium constant for the combustion of ammonia at the final temperature of the mixture. Round your answer to 2 significant digits. K = -0 ☐ x10 G
