2. An evacuated vessel (of fixed volume) is charged with 0.100 atm of NO (g) and 0.200 atm of NO2 (g). The two gases proceed to react according to the equation below, at 273 K throughout. NO (g) + NO2 (g) –> N2O3 (g) What is The pressure in the vessel before any reaction occurs and the pressure in the vessel after the reaction has gone to completion? What are the identities of the gases in the vessel after complete reaction?
