Entropy Flashcards
1
Q
What 3 things affect entropy? How do they affect it?
A
Physical state - solids have lowest entropy - most order
Dissolution - dissolved particles move more freely = increased entropy
Number of particles - more particles = more moles = more entropy
2
Q
How do spontaneous endothermic reactions occur?
A
Entropy increases so much that the reaction will happen by itself
3
Q
What is entropy change of the system?
A
Entropy change between reactants and products
System = Sproducts - Sreactants
4
Q

A
T
5
Q

A
deltaSsystem + deltaSsurroundings
6
