WebRespiration is exo, it gives out energy, whereas photosynthesis is endo, it requires energy. Now let's talk about decomposition of vegetable matter. This is a tricky one. See, this has the word decomposition in it. Now in the video of exo and endothermic reactions, we have seen that, in general, decomposition reactions. WebJan 30, 2024 · Heat of Reaction. The Heat of Reaction is the change in the enthalpy of a chemical reaction. In endothermic reactions, (\(ΔH>0\)) thermal energy is absorbed via the reaction.Anther way to view endothermic reactions is that more (thermal) energy is needed to overcome the forces of attraction between molecules and to separate them …
