How is it that when a rxn is exothermic and you raise its temperature the rxn shifts to the left?

I thought when a system is exothermic and it releases heat, once u increase tempreature by adding heating that it would try to get to equilibrium by releasing more heat, as in favoring the product and the eventual shift to the right.

Is this a mistake on topscore behalf, or am in bad shape?

It's not a mistake. If the reaction is exothermic, then heat is a product (ie. appear on the right). If you increase the temperature, the reaction will proceed to decrease the heat by shifting to the left. Remember, the heat is absorbed to form bonds.

According to Le Chateleir's principle, if stress is applied, a system will shift to relieve the stress. Exothermic reactions will shift to the left to form equilibrium. I think it makes sense.

WORD! got it! I am just gona start writing the word heat next to the products if its exothermic. That way i can visualize that its being added to the right, and that it will shift to the left. THNX guys!! God i love this forum and the people who help!
