How to Calculate and Solve for Homogeneous – Heterogeneous Relationship | Phase Transformation

Last Updated on December 12, 2022

The image above represents homogenous – heterogenous relationship.

To compute for homogenous – heterogenous relationship, two essential parameters are needed and these parameters are Activation Energy for Homogenous (ΔG*homand Function S(θ).

The formula for calculating homogenous – heterogenous relationship:

ΔG*het = ΔG*hom S(θ)


ΔG*het = Activation Energy (Heterogeneous)
ΔG*hom = Activation Energy (Homogeneous)
S(θ) = Function

Given an example;
Find the homogenous – heterogenous relationship when the activation energy for homogenous is 35 and the function is 7.

This implies that;

ΔG*hom = Activation Energy (Homogeneous) = 35
S(θ) = Function = 7

ΔG*het = ΔG*hom S(θ)
ΔG*het = (35)(7)
ΔG*het = 245

Therefore, the homogenous – heterogenous relationship is 245 J.
