Problem- Temperature furnace operates at 5 bars with temperatures in the range of 1000 to 2000 K by burning methane in 20% excess air. By regulation the concentration of NO in the gases leaving the reactor may not exceed 500 ppm by volume. Assuming the reactor is large enough that equilibrium is achieved, at what temperature can the reactor be operated without violating the regulation? [The heat of reaction may be assumed independent of temperature.] [ (d) Determine the equilibrium constant and the equilibrium mole fraction of NO at the temperature from part c. K at 298K is 4.03*10^-31
