Given below are two statements: One is labelled as Assertion $$\mathbf{A}$$ and the other is labelled as Reason $$\mathbf{R}$$
Assertion A : The reduction of a metal oxide is easier if the metal formed is in liquid state than solid state.
Reason $$\mathbf{R}$$ : The value of $$\Delta G ^\Theta$$ becomes more on negative side as entropy is higher in liquid state than solid state.
In the light of the above statements, choose the most appropriate answer from the options given below
Which of the following relation is not correct?
$$\Delta$$G$$^\circ$$ vs T plot for the formation of MgO, involving reaction
2Mg + O2 $$\to$$ 2MgO, will look like :
Match List-I with List-II.
| List - I | List - II | ||
|---|---|---|---|
| (A) | Spontaneous process | (I) | $$\Delta H < 0$$ |
| (B) | Process with $$\Delta P = 0$$, $$\Delta T = 0$$ | (II) | $$\Delta {G_{T,P}} < 0$$ |
| (C) | $$\Delta {H_{reaction}}$$ | (III) | Isothermal and isobaric process |
| (D) | Exothermic Process | (IV) | [Bond energies of molecules in reactants] $$ - $$ [Bond energies of product molecules |
