Consider the following reaction:
2CO (g) + O2 (g) ---> 2CO2 (g)
Imagine that this reaction occurs in a container that has a piston that moves to allow a constant pressure to be maintained when the reaction occurs at constant temperature.
1) What happens to the volume of the container as a result of the reaction. Explain.
2) If the piston is not allowed to move, what happens to the presure as a result of the reaction?
