The Martian atmosphere consists of approximately 96% carbon dioxide, and the mean molar mass is 43.34 g mol-1 . The mean atmospheric pressure on the Martian surface is 6 hPa and the surface mean temperature is 210 K. What is the atmospheric pressure at 25 km from the ground (i.e. the top of Olympus Mons, a large volcano on Mars) in hPa? Use the gravity on Mars of 3.711 m s-2 . Answer to two significant digits.

Public concern about the increase in carbon dioxide (CO2) in the atmosphere has led to numerous proposals to sequester or eliminate CO2. An inventor believes he has developed a new catalyst that can make the following gas phase reaction proceed with 40% conversion of CO2: CO2(g) + H2(g) > H2O(g) + CH4(g) The source of H2 for the reaction would be from the electrolysis of water using electricity generated from solar cells. Assume that 1.5 mole of CO2 enter the...
