Ellingham Diagram: Graph of G vs T
The Ellingham diagram is a graph that represents the variation of Gibbs free energy (G) with temperature (T) for the formation of oxides from the corresponding metals. This diagram is named after the English chemist Thomas Ellingham, who first proposed this concept in 1944.
The Ellingham diagram is generally used to predict the feasibility of a particular reduction reaction. It provides a graphical representation of the thermodynamic stability of various metal oxides at different temperatures. The slope of the line on the graph represents the enthalpy of the reaction, while the intersection of the line with the x-axis (temperature axis) represents the equilibrium temperature of the reaction.
Options (a), (c), and (d) are incorrect because:
- Option (a) represents a graph of entropy (S) versus temperature (T), which is not the case for the Ellingham diagram.
- Option (c) represents a graph of entropy (S) versus temperature (T), which is not correct for the Ellingham diagram.
- Option (d) represents a graph of Gibbs free energy (G) versus pressure (P), which is not the case for the Ellingham diagram.
Therefore, the correct answer is option (b), which represents a graph of Gibbs free energy (G) versus temperature (T), as it is the characteristic feature of the Ellingham diagram.
