Which of the following is not true about gas behavior according to the kinetic molecular theory? a. gases are composed of molecules whose size is negligible compared to the average distance between them. c. the average kinetic energy of a molecule is proportional to the absolute temperature. b. molecules move randomly in all directions and at various speeds. d. gases are heavy molecules with a low kinetic energy that is not dependent on temperature.

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.
