WebThe affect temperature has on a reaction, and which side is favored, depends on its enthalpy, whether it is exothermic or endothermic. If a reaction is exothermic, more energy is being lost by the system than is being input. So, we can think of the enthalpy in an exothermic reaction as a product. If we increase the temperature, then we have ... 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.
