1. Keq = 8.63x10^-4 for a reaction. Which of the following must be true?

	∆Gº=0
	∆Gº=1
	∆Gº>0
	∆Gº<0

2. What is the value of Keq if ∆Gº=-9.48 kJ (R=8.314 J/mol-K)?

	6700
	1.00
	1.01
	45.9

3. Calculate ∆Gº for the reaction, C₃H₈(g)+5O₂(g)→3CO₂(g)+4H₂O(g), where ∆G_fº=-23.5 kJ/mol for CH₄(g), -394 kJ/mol for CO₂(g), and -229 kJ/mol for H₂O(g):

	600 kJ
	-600 kJ
	-2070 kJ
	2070 kJ
