Chemistry Question on General Principles and Processes of Isolation of Elements

Ellingham diagram represents a graph of

A

ΔGVsT\Delta\, G\, Vs\, T

B

ΔGVsT\Delta \, G ^\circ \,Vs\, T

C

ΔSVsP\Delta S\, Vs\, P

D

ΔGVsP\Delta G\, Vs\, P

Answer

ΔGVsT\Delta \, G ^\circ \,Vs\, T

Explanation

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 sulphides. Ellingham diagram represents change in free energy ΔG\Delta G with temperature.
