exothermic reaction

Postby WGaines_2E » Mon Mar 09, 2020 10:07 pm

say we have reaction A+B -> C + D and delta H is negative. Does that mean you add heat to the left or right side of the reaction?

If you add heat to this reaction, the reactants will increase in concentration since it is an exothermic reaction. I don't think you can add heat to a specific side.

In an exothermic reaction, heat is one of the products. For an endothermic reaction, heat is required, so it can be seen as part of the reactants.

If delta H is negative that means that there is a release of energy so the reaction is exothermic.

Since the delta H is negative, the reaction is therefore exothermic, which means that there is a release of energy in the reaction process. This wouldn't necessarily mean that energy is 'added' but actually released as a product! (through the formation of bonds in reactants A and B to create C)
