change in free energy is positive
It is due to change of state.
An Ellingham diagram illustrates the temperature dependence of the Gibbs free energy change for various reactions, primarily oxidation and reduction processes. Each line on the diagram represents a specific reaction, with its position indicating the stability of the oxide or compound at different temperatures. The lower a line is on the diagram, the more stable the corresponding oxide is at that temperature. By comparing the positions of different lines, one can determine the feasibility of reducing a metal oxide using another metal or reactant at various temperatures.
A steep increase in the slope of a line on an Ellingham diagram indicates that the reaction becomes increasingly more favorable at higher temperatures. This typically suggests that the Gibbs free energy change (ΔG) for the reaction decreases significantly with an increase in temperature, making the formation of the compound more thermodynamically favorable. It can also imply a stronger dependence of the reaction on entropy changes at elevated temperatures.
In a graph showing speed versus time, a straight line indicates that the acceleration is constant. This means that the speed of the object is changing at a uniform rate over time. If the line slopes upwards, the object is accelerating; if it slopes downwards, the object is decelerating. The steepness of the line represents the magnitude of the acceleration.
Slopes that are dangerously high and/or steep.
It is due to change of state.
On a spacetime diagram, the worldline of an object accelerating away from you would appear as a curve that slopes upwards and to the right, indicating the object's increasing distance from you over time.
