change in temperature
In an endothermic reaction, heat is required to break bonds, so endothermic reactions favor a reverse reactions. Do endothermic reactions, then, also favor the formation of reactants? In class, it was said that endothermic reactions favor product formation ???

Re: change in temperature
Your wording is a little confusing. Can you please rephrase or clarify your question? Heat is indeed required to break bonds, which entails an endothermic reaction. Whether formation of products or reactants is more favorable depends more on the deltaG of the reaction.

Re: change in temperature
A change in temperature will always favor the exothermic reaction whether it is an increase or decrease.

"A change in temperature will always favor the exothermic reaction whether it is an increase or decrease."
---Pretty sure if temperature is raised, a reaction mixture at equilibrium will actually shift the reaction in the endothermic direction in order to counter the effect of heat being added to the system.

Re: change in temperature
In class, we learned that if a reaction requires heat (is endothermic) while forming product, then heating would favor product formation. I read something that explained this using equations: heat+6CO2(g)+6H2O(l)⇌C6H12O6(aq)+6O2(g) In endothermic reactions, heat is on the side of the reactants, so adding heat would favor the formation of products, which are on the other side of the equation.
