22.4 - Entropy Flashcards
1
Q
What is entropy?
A
The dispersal of energy and disorder within the chemicals making up the chemical system
2
Q
What are the units of entropy? delta S
A
JK⁻¹mol⁻¹
3
Q
What are the standard conditions for standard entropy?
A
100KPa
293K
4
Q
What is the trend for entropy in the three states?
A
Solids = smallest entropies
Liquids = greater entropies
Gases = greatest entropies
high disorder = high entropy
5
Q
How do you calculate the standard entropy?
A
∆S° = ∑S° products - ∑S° reactants
SPAR, ∑ = sum of
