5J.11b Halogens

Postby JChen_2I » Tue Jan 07, 2020 10:42 pm

Predict whether each of the following equilibria will shift toward products or reactants with a temperature increase:
X2(g) -> 2X(g), where X is a halogen

How do halogens affect equilibrium?

Halogens themselves don't tell us if the reaction is exo or endothermic. However, breaking bonds requires energy so going from X2 to 2X is endothermic. This means that increasing the temperature will shift the equilibrium towards the products. The fact it is a halogen doesn't really matter.
