Endothermic vs Exothermic

Postby Bryce Ramirez 1J » Sat Mar 14, 2020 6:20 pm

How do you know when a reaction is favored because it is either endo or exothermic?

You can tell if the reaction is favored based on its delta G. Exothermic and endothermic correlate to the delta H value

Im not exactly sure if this is what you are asking but I hope this answer helps. A reaction is exothermic if Kc decreases with an increase in temperature, as the reaction shifts left, or Kc increases with a decrease in temperature, as the reaction shifts right. This is because in an exothermic reaction heat is a reactant. The opposite is true for an endothermic reaction: Kc increases with an increase in temperature, as the reaction shifts right, or Kc decreases with a decrease in temperature, as the reaction shifts left. I hope This helps, but If you could clarify your question further that would be great.
