Entropy

Define entropy (~)
measure of disorder in a system
1 of 7
as we go solid, liquid, gas, entropy ______
increases (ie the disorder is becoming greater)
2 of 7
ΔS =
S(products) - S(reactants)
3 of 7
reaction can be said to be feasilby spontaneous if
ΔS > 0
4 of 7
ΔG =
ΔH -TΔS
5 of 7
for a reaction to be feasible ΔG must be
ΔG < 0 therefore at ΔG = 0, this is the point where it is just becoming feasible
6 of 7
define ΔG
ΔG (free energy change) is measure used to predict whether a reaction is feasible. it takes into account the changes in enthalpy and entropy in the system
