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

The image above represents homogenous – heterogenous relationship. To calculate homogeneous – heterogenous relationship, two essential parameters are needed and these parameters are Activation Energy for Homogenous (Î”G*hom)Â andÂ Function S(Î¸).

### The formula for calculating homogenous – heterogenous relationship:

Î”G*hetÂ = Î”G*homÂ S(Î¸)

Where:

Î”G*hetÂ = Activation Energy (Heterogeneous)
Î”G*homÂ = Activation Energy (Homogeneous)
S(Î¸) = 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;

Î”G*hom = Activation Energy (Homogeneous) = 35
S(Î¸) = Function = 7

That is, Î”G*hetÂ = Î”G*homÂ S(Î¸)
Î”G*het = (35)(7)
Î”G*het = 245

Therefore, theÂ homogenous – heterogenous relationshipÂ isÂ 245 J.
