A). Using only the following information: delta Hf for NO(g) is +90.4 kJ/mol; delta H= -56.6 kJ/mol for the reaction: NO(g) + 1/2 O2(g). Determine delta Hf for NO2(g).

B). Using only your answer to a, and the following information: Delta H = -283.0 kJ/mol for the reaction: CO(g) +1/2 O2 (g) --> CO2 (g), determine delta H for the reaction: 4CO (g) + 2NO2 (g) --> 4CO2(g) + N2 (g).

C). A10.0L vessel contains 5.0 ATM of CO and 3.0 atm of NO2 at 25 degrees celsius. How much heat in joules will be liberated if this is allowed to react to completion according to the reaction in part b?

D). In a separate experiment using a very large reaction vessel with a movable piston, 6.00 moles of CO2 reacts completely with 3.00 moles of nitrogen gas according to the following equation at 25 degrees Celsius and with a constant external pressure of 2.00 atm: 4CO2 + N2 --> 4CO + 2 NO2. This reaction proceeds to completion. Calculate delta U, q, and w for this reaction under these conditions.
