In Ellingham diagram, the plot is drawn between

• A

  temperature, $\Delta H^{\circ}$
• Correct answer
  B

  temperature, $\Delta G^{\circ}$
• C

  pressure, $\Delta S^{\circ}$
• D

  temperature, $\Delta E^{\circ}$

Solution

Standard Gibbs free energy ∆G° is plotted against temperature (T)

Hence, the correct answer is option: 'B'.
