Ellingham diagram represents:

A

Change of `Delta G` with temperature

B

Change of `Delta H` with temperature

Change of `(Delta G- T Delta S)` with temperature

Text Solution

Verified by Experts

The correct Answer is:
A
The free energy change that occurs when 1mol of reactant (in this case `O_(2)`) is used may be plotted graphically against temperature for a number of reactions. This is called an Ellingham diagram.
