For a reaction,

Question:

For a reaction,

$4 \mathrm{M}(\mathrm{s})+\mathrm{nO}_{2}(\mathrm{~g}) \rightarrow 2 \mathrm{M}_{2} \mathrm{O}_{\mathrm{n}}(\mathrm{s})$

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 changes from positive to zero

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

  3. the slope changes from negative to positive

  4. the slope changes from positive to negative


Correct Option: , 2

Solution:

(2) the free energy change shows a change from negative to positive value
