Diagramm exotherme reaktion
WebWhen considering whether a reaction is endothermic or exothermic, it is vital to separate the reaction system from the environment. What matters is the change in temperature of the system, not how hot or cold the system is in general. If the system cools down, that means heat is being released, and the reaction taking place is an exothermic ... WebEngineering Chemical Engineering Label each part of the energy diagram shown below.
