The point of intersection and sudden increase in the slope, in the diagram given below, respectively, indicates:

The point of intersection and sudden increase in the slope, in the diagram given below, respectively, indicates:

Options

  1. AΔG=0\Delta G = 0 and melting or boiling point of the metal oxide
  2. BΔG>0\Delta G > 0 and decomposition of the metal oxide
  3. CΔG<0\Delta G < 0 and decomposition of the metal oxide
  4. DΔG=0\Delta G = 0 and reduction of the metal oxide

Correct answer

A. ΔG=0\Delta G = 0 and melting or boiling point of the metal oxide

Step-by-step solution

At intersection point ΔG=0\Delta G = 0 and sudden increase in slope is due to melting or boiling point of the metal.
