Consider this reaction at equilibrium:
2SO
2(g) + O
2(g)
2SO
3(g),
ΔHº
rxn = –198 kJ/mol
If the volume of the system is compressed at constant temperature, what change will occur in the position of the equilibrium?
◦ A shift to produce more SO
2◦ A shift to produce more O
2◦ No change
◦ A shift to produce more SO
