Problem Solving 1. 1 mol propane (CH) and stoichiometric amount of oxygen (0.) needed to combust propane was preheated to 400 K. After combustion, the products released are at 1500 K. The combustion products are H2O(0) and Co. (g). With 100% conversion was achieved, estimate the total heat released 2. Calculate the heat requirement for a reactor in combusting 1 mol of methane, CH, with 25%, excess air until the products reach a temperature of 1000 K. The reactants entered the reactor at 298.15 K and 100% conversion of methane is achieved. Assume air is approximately 21% 0, and 79% N; and products are H2O(l) and Co (g). Hint for both #1 and #2 - Combustion products at 298 K is CO. (g) and H.O(1). If the exiting temperature is above 373.15 K, H-O will leave as H:0(g). Therefore, you should account for the phase change of HO(l) to Hig)
