The image above represents free energy for formation of stable nucleus. To calculate free energy for formation of stable nucleus, two essential parameters are needed and these parameters are Volume Free Energy (ΔGv) and Surface Free Energy (γ).
The formula for calculating free energy for formation of stable nucleus:
ΔG* = 16πγ³/3(ΔGv)²
Where:
ΔG* = Free Energy for Formation of Stable Nucleus
γ = Surface Free Energy
ΔGv = Volume Free Energy
Let’s solve an example;
Find the free energy for formation of stable nucleus when the surface free energy is 12 and the volume free energy is 6.
This implies that;
γ = Surface Free Energy = 12
ΔGv = Volume Free Energy = 6
ΔG* = 16πγ³/3(ΔGv)²
That is, ΔG* = 16π(6)³/3(12)²
ΔG* = 16π(216)/3(144)
So, ΔG* = (10857.34)/(432)
ΔG* = 25.13
Therefore, the free energy for formation of stable nucleus is 25.13 J.
