5J.11 Part b

Postby Lia Inadomi 1I » Tue Jan 15, 2019 8:29 pm

The question is does a temperature increase shift equilibria towards products or reactants for X2<-->2X?
Why is X2-->2X endothermic? Isn't it a catabolic reaction and therefore exothermic?

When a reaction involves the breaking of a diatomic molecule X2, this requires energy to become 2X, so the reaction is endothermic because it takes in heat to break apart.

It requires energy to break a X-X bond, making it an endothermic reaction which favors formation of products.
