On Ellingham diagrams if two graphs intersect each other, what does the point of intersection indicate ?

Explanation

To answer the question regarding the significance of the intersection point of two graphs on an Ellingham diagram, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Understanding the Ellingham Diagram**:
- The Ellingham diagram is a plot that shows the relationship between the Gibbs free energy change (ΔG) of a reaction and temperature (T). It is used to predict the feasibility of reactions, particularly in metallurgy.

2. **Identifying the Graphs**:
