1. The water-gas-shift reaction, CO(g) + H2O(g)  CO2(g) + H2(g) is carried out with the reactants consists of 2 mol of H2O vapor and 1 mol of CO. The temperature is 1,100 K and the pressure is 1 bar. 1). Find out the reaction constant K from the Figure13.2 on the textbook based on the condition given. (5 points) 2). Calculate the fraction of steam reacted. Assume the mixture behaves as an ideal gas. (10 points)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
