Multiple Choice
Multiple ChoiceNitrogen gas combines with fluorine gas to form nitrogen trifluoride according to the reaction below at 25oC:
N2 (g) + 3 F2 (g) → 2 NF3 (g) ΔHo = -249.0 kJ ΔSo = -278 J/K
Calculate ΔGo and state if the reaction favors reactants or products at standard conditions.
A
∆Go = - 332 kJ; the reaction favors the formation of reactants.
B
∆Go = - 166 kJ; the reaction favors the formation of products.
C
∆Go = - 166 kJ; the reaction favors the formation of reactants.
D
∆Go = - 332 kJ; the reaction favors the formation of products.
