New cards

What is entropy

The measure of the disorder of a system

2
New cards

Factors affecting the entropy of a system

Physical state

Gases>Liquid>Solids

3
New cards

Temperature

Temperature ∝ Entropy

4
New cards

Number of Particles

N2O4—→ 2NO2

The more particles in a system the higher the entropy. eg there are more ways to arrange 10 particles ie permutations than 2 particles.

5
New cards

Pressure/Volume

Increasing the volume or decreasing the pressure increases entropy

6
New cards

Complexity (no of bonds)

Bonds ∝ Entropy eg Pentane has higher entropy than hydrogen because there are more bonds and those bonds can arrange themselves in different ways

7
New cards

Flexibility

The more flexible a molecule, the more ways the bonds can be arranged and have higher entropy eg Hex-1-ene has higher entropy than cyclohexane
