1
Q
Never spontaneous.
A
ΔH (+)
ΔS (–)
2
Q
Spontaneous at all temps
A
ΔH (–)
ΔS (+)
3
Q
Spontaneous at low temps.
A
ΔH (–)
ΔS (–)
4
Q
Spontaneous at high temp only.
A
ΔH (+)
ΔS (+)
5
Q
How to find melting/boiling points using thermodynamic info.
A
- T = (ΔH–ΔG)/ΔS
* ΔG = 0
6
Q
What is a way to calculate ΔS
A
ΔS = Q/T
7
Q
*Keep in mind the sign of ΔH when flowing in or out of system
A
:(
8
Q
When interpreting a reaction energy diagram, how do you tell the heat and activation energy of reaction?
A
- heat is the distance between product/reactant (can be –)
* activation energy is distance between reactants to the top (+)
9
Q
What happens to initial rate of reaction in terms of Temperature and Volume?
A
- Temp- goes up, higher rate
* Volume- goes up, lower rate
10
Q
Neither products or reactants dominate when K is from .1 to 10
A
Ye
