Sheet of steel 4.3 mm thick has nitrogen atmospheres on both sides at 1200°c and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 5.1 × 10-11 m2/s, and the diffusion flux is found to be 4.9 × 10-7 kg/m2-s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4.2 kg/m3. how far into the sheet from this high-pressure side will the concentration be 2.7 kg/m3? as

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.
