Carbon monoxide and oxygen combine to form carbon dioxide with an energy release of 280 kJ/mol of CO according to the reaction 2(CO) + O₂ → 2(CO₂). Two mol of CO and one mol of O₂ at 300 K are confined in an 80-L container; the combustion reaction is initiated with a spark.

(a) What is the pressure in the container prior to the reaction?

(b) If the reaction proceeds adiabatically, what are the final temperature and pressure?

(c) If the resulting CO₂ gas is cooled to 0^oC, what is the pressure in the container?
