Temperature of a Reaction

Postby Liliana Madrigal 1A » Sun Dec 07, 2014 5:41 pm

Would increasing the temperature of a reaction make the reaction favor the products?

It depends on whether the reaction is endothermic or exothermic. Increasing temperature always favors the endothermic direction of the reaction.

In an endothermic reaction, energy is required and can be considered a reactant. Increasing temperature (and thus energy) drives the reaction forward, so the products are favored.

In an exothermic reaction, energy is released and can be considered a product. Increasing the temperature increases the amount of a product (energy), so the reverse reaction (the endothermic one) is favored to reduce the effects the increase in a product has on the system (Le Chatelier's principle).
