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

Options

A. `Delta G gt 0` and decomposition of the metal oxide
B. `Delta G = 0 ` and melting or boiling point of the metal oxide
C. `Delta G lt 0` and decomposition of the metal oxide
D. `Delta G = 0` and reduction of the metal oxide

Answer

B

Explanation

From the Ellingham diagram given, the point of intersection represents `Delta G = 0` and the temperature at which sudden increases in the slope occurs is indicated by melting or boiling .
