Consider this reaction: n2 (g) + 3h2 (g) 2nh3 (g) what will happen if more hydrogen gas is added to the reaction mixture? a. there will be a shift toward the products. b. there will be a shift toward the reactants. c. there will not be a shift in equilibrium. d. the value for keq will change.

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.
