1
Q
If ΔG is negative, what does it mean for the reaction?
A
Reaction is feasible
2
Q
If ΔG is positive, what does it mean for the reaction?
A
Reaction is not feasible
3
Q
If ΔG is zero, what does it mean for the reaction?
A
Reaction is in equilibrium
4
Q
What is the equation for ΔStotal?
A
ΔStotal = ΔSsystem + ΔSsurroundings
ΔStotal = (∑ΔSproducts - ∑ΔSreactant) + (-ΔH/T)
5
Q
What does total entropy change determine?
A
Whether reaction is spontaneous or not
6
Q
What is the entropy change when a system goes through a closed cycle?
A
Zero
7
Q
What is the equation for ΔSsurroundings?
A
-ΔH/T
(Temperature in Kelvin)
