|
|
K |
e^ - Delta G / RT |
|
|
Delta G 2 |
-RT ln(K) |
|
|
Delta G 3 |
Delta H* - T Delta s* |
|
|
Delta S (reversable) |
q reversable reaction /T |
|
|
Delta H |
sum of the products - sum of the reactants |
|
|
Spontaneous |
Reoccurs on own without outside help. Entropy increases |
|
|
Reversible Process |
Exactly Opposite of what occurs |
|
|
Reversible Process (Universe) |
Delta S (universe)= Delta S (system) + Delta S (surroundings) = 0 |
|
|
Irreversible Process (Universe) |
Delta S (universe) = Delta S (system) + Delta S (surroundings) > 0 |
|
|

|
|
Rotationial motion |
Rotates around an axis |
|
|
W |

|
|
Entropy and microstates increase when |
1) Rise of Temperature 2) Greater volume 3) Greater number of molecules |
|
|
Entropy increases when |

|
|
Third law of thermodynamics |
Entropy = 0 when at absolute 0 |
|
|
Standard Entropy |
Molecular entropy in standard states Increase with molar mass |
|
|
