11.77 textbook problem

Postby Tim Foster 2A » Fri Dec 08, 2017 9:58 am

Why does increasing the temperature of the rxn X2(g)<--->2X(g), where X is a halogen, favor the products? How should we know that is endothermic in the forward direction?

It requires energy, in this case, heat, to break apart a molecule. Therefore, the forward reaction is endothermic and will be favored.

Essentially, the problem says the temperature is increasing. This must mean that the reactants need to absorb more energy - an endothermic reaction. Raising the temperature favors the reverse reaction (endothermic) and
lowering the temperature favors the forward reaction (exothermic). So in this case, the products are favored.
