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 1.5 l flask with 3.5 atm of methane gas and 1.3 atm of water vapor at 43.0°c. he then raises the temperature, and when the mixture has come to equilibrium measures the partial pressure of carbon monoxide gas to be 1 .0 atm. calculate the pressure equilibrium constant for the steam reforming of methane at the final temperature of the mixture. round your answer to 2 significant digits.

Asample of gas in a cylinder as in the example in part a has an initial volume of 52.0 l , and you have determined that it contains 1.40 moles of gas. the next day you notice that some of the gas has leaked out. the pressure and temperature remain the same, but the volume has changed to 13.0 l . how many moles of gas (n2) remain in the cylinder?
