For a reaction,
4M(s) + NO2(g) → 2 M2On(s)
The free energy change is plotted as a function of temperature. The temperature below which the oxide is stable could be inferred from the plot as the point at which:
(1) the slope change from positive to zero
(2) the slope changes from negative to positive
(3) The free energy change shows a change from negative to positive value
(4) the slope changes from positive to negative

(3) The free energy change shows a change from negative to positive value
Explanation:
For oxide to be stable its ΔG value should be negative.
