Consider the following reaction between carbon monoxide gas and
oxygen gas, which produces carbon dioxide:
2CO (g) + O2 (g) → 2CO2 (g)
Assume the reaction takes place at a constant temperature of 298
K and at a constant pressure of 1 atmosphere (1 bar). You can find
tabulated values of the thermodynamic properties of these materials
(from pg 405 of the textbook) on the the thermodynamics canvas
page, but be careful of units. Also, assume that 1 mol of oxygen is
consumed in the reaction.
Answer the following questions, giving a reason or working for each
answer:
a) Which is the relevant free energy involved in this reaction?
Justify your choice of free energy. (1 mark)
b) Calculate the free energy (1 mark)
c) Can work be extracted? or does it need to be supplied? (1
mark)
d) Does the system consume energy to expand against the atmosphere,
or does the atmosphere do work on the system as the system
collapse? (1 mark)
e) Calculate the work involved in mechanical
(expansion/compression) work (2 marks)
