Question: 1 keq 863x104 for a reaction which of the...

Question details

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 ∆Gfº=-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
