Question

This question is for practice and not graded. Please elaborate on answer. Thank you.

The image presents a graph depicting the change in standard Gibbs free energy (\(\Delta G^\circ\)) for a chemical process plotted against absolute temperature (\(T(K)\)). The graph displays a linear relationship with a negative slope, where:

- The vertical axis represents \(\Delta G^\circ\), with positive values above the origin and negative values below it.
- The horizontal axis represents temperature in Kelvin (\(T(K)\)).
- The line crosses the \(\Delta G^\circ\) axis, indicating a decrease in \(\Delta G^\circ\) as temperature increases.

The accompanying question asks which of the given statements is an incorrect conclusion based on the graph:

1. There exists a certain temperature at which \(\Delta H^\circ = T\Delta S^\circ\).
2. \(\Delta S^\circ > 0\).
3. \(\Delta S^\circ\) increases with temperature while \(\Delta H^\circ\) remains constant.
4. The reaction is spontaneous at high temperatures.
5. \(\Delta H^\circ > 0\).
