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:
Option 1 -
ΔG = 0 and reduction of the metal oxide
Option 2 -
ΔG = 0 and melting or boiling point of the metal oxide
Option 3 -
ΔG > 0 and decomposition of the metal oxide
Option 4 -
ΔG < 0 and decomposition of the metal oxide
-
1 Answer
-
Correct Option - 3
Detailed Solution:At the point of intersection in an Ellingham diagram? G for two processes becomes equal, so? G for the reduction becomes zero. A sudden increase in the slope indicates a change in the state of the metal oxide, i.e., from solid to liquid or liquid to vapor.
