A stoichiometric mixture of hydrogen and air is compressed to 18.63 bar and 845 °C. It burns adiabatically at constant volume. Show that the final equilibrium temperature is 3300 K and the degree of dissociation is 8.85%. Calculate the final pressure after combustion. Show the process, including the effect of dissociation, on a U-T diagram. The equilibrium constant is
