Public concern about the increase in carbon dioxide (CO 2 ) in the atmosphere has led to numerous proposals to sequester or eliminate CO 2 . An inventor believes he has developed a new catalyst that can make the following gas phase reaction proceed with 40% conversion of CO 2 : CO 2(g) + H 2(g) H 2 O (g) + CH 4(g) The source of H 2 for the reaction would be from the electrolysis of water using electricity generated from solar cells. Assume that 1.5 mole of CO 2 enter the reactor at 700 °C together with 4 mol of H 2 at 100 °C. At what temperature do the exit gases leave the reactor? Assume that the system is at steady state, the reactor is perfectly insulated, and no work is involved....
