Use hess's law to calculate the enthalpy change for the reaction: 3c(s) + 3h2(g) → c3h6(g) given the following thermochemical equations: 2c3h6(g) + 9o2(g) → 6co2(g) + 6h2o(l) δh = -4182.6 kj/mol c(s) + o2(g) → co2(g) δh = -393.51 kj/mol h2(g) + ½o2(g) → h2o(l) δh = -285.83 kj/mol

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.
