Question

For a reaction,
4M(s) + nO₂(g) $ \to $ 2M₂O_n(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 :

the free energy change shows a change from negative to positive value

the slope changes from positive to negative

the slope changes from negative to positive

the slope changes from positive to zero
