Ellingham diagram is drawn between

  • A
    Change in potential and pH
  • B
    Change in free energy and oxidation state
  • Correct answer
    C
    Change in free energy and temperature
  • D
    Change in free energy and polarizability

Solution

An ellingham diagram is a graph showing the temperature dependence of the stability for compounds. This analysis is usually used to evaluate the ease of reduction of metal oxides and suphides.Ellingham diagram represents change in free energy with temperature.

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