$12.$ Which is more stable, the $C_2{H}_6$ in the first reaction or the $F{e}_2{O}_3$ in the second?

Why?

$13.$ Based on the enthalpy change alone, would you expect the above reaction to be spontaneous at room temperature? Why?

$14.$ Do the products or the reactants have more enthalpy?

$15.$ Is the above reaction endothermic or exothermic?
