1. Consider the reaction:

2BrF₃(g)------------>Br₂(g) + 3F₂(g)

Using standard thermodynamic data at 298K, calculate the free energy change when 2.06 moles of BrF₃(g) react at standard conditions.
G°_rxn = _____kJ

2. Consider the reaction

Fe₂O₃(s) + 2Al(s)--------->Al₂O₃(s) + 2Fe(s)

Using standard thermodynamic data at 298K, calculate the entropy change for the surroundings when 1.52 moles of Fe₂O₃(s) react at standard conditions.
S°_surroundings = _______J/K

3. For the reaction

2C₂H₆(g) + 7O₂(g)------------>4CO₂(g) + 6H₂O(g)

H° = -2.86×10³ kJ and S° = 92.7 J/K
