Given below are two statements related to Ellingham diagram:

Statement I : Ellingham diagrams can be constructed for formation of oxides, sulfides and halides of metals.

Statement II : It consists of plots of $$\Delta_{\mathrm{f}} \mathrm{H}^{0}$$ vs $$\mathrm{T}$$ for formation of oxides of elements.

In the light of the above statements, choose the most appropriate answer from the options given below:

Which one of the following is most likely a mismatch ?

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R

Assertion A : In the Ellingham diagram, a sharp change in slope of the line is observed for $$\mathrm{Mg} \rightarrow \mathrm{MgO}$$ at $$\sim 1120^{\circ} \mathrm{C}$$

Reason R: There is a large change of entropy associated with the change of state

In the light of the above statements, choose the correct answer from the options given below
