Methanol at 675°c and 1 bar is fed at a rate of 100 mol/s is fed to an adiabatic reactor where 25% of it is dehydrogenated to formaldehyde according to the reaction chaoh (g) hcho (g) +h2 (8). calculate the temperature of the gases leaving the reactor assuming that constant heat capacities of 17, 12, and 7 cal/mol°c for ch3oh, hcho, and h2, respectively are applicable. heat of formation for hcho (g) and ch3oh (g) are-27.7 and 48.08 kcal/mol
