Entropy

a measure of how disordered or chaotic a system in/ Jmol-1K-1

2
New cards

ΔStotal

ΔSsystem + ΔSsurroundings

3
New cards

Delta S system

products - reactants

4
New cards

Delta S surroundings

- Delta H/ T

Delta H convert to Jmol-1

T in Kelvin

5
New cards

Gibbs free energy

Delta H - T x Delta S system

Delta H and Delta G in KJmol-1

Delta S in Jmol-1K-1 so convert to KJ

6
New cards

Gibbs free energy change (equilib constant)

-RTlnK

delta Gibb - in KJmol-1 convert to joules

R is gas constant

T in kelvin

K is equilibrium constant
