A) Consider the reaction
4HCl(g) + O2(g)2H2O(g) + 2Cl2(g)

Using the standard thermodynamic data in the tables linked above,
calculate G for this
reaction at 298.15K if the pressure of each gas
is 19.59 mmHg.ANSWER: kJ/mol
B) Consider the reaction:
CO(g) + Cl2(g)COCl2(g)

Using standard thermodynamic data at 298K, calculate the free
energy change when 2.360 moles
of CO(g) react at standard
conditions.
G°rxn = kJ
C) Consider the reaction:
2H2O(l)2H2(g) + O2(g)

Using standard thermodynamic data at 298K, calculate the free
energy change when 1.56 moles
of H2O(l) react at standard
conditions.
G°rxn = kJ
