1. Consider the reaction N₂(g) + 2O₂(g)2NO₂(g) Use the standard thermodynamic data in the tables linked above. Calculate G for this reaction at 298.15K if the pressure of NO₂(g) is reduced to 12.29 mm Hg, while the pressures of N₂(g) and O₂(g) remain at 1 atm. ANSWER: kJ/mol

2. Consider the reaction H₂(g) + C₂H₄(g)C₂H₆(g) Using the standard thermodynamic data in the tables linked above, calculate G_rxn for this reaction at 298.15K if the pressure of each gas is 17.73 mm Hg. ANSWER: kJ/mol
