WebLearn about exothermic and endothermic reactions and the transfer of energy with GCSE Bitesize Combined Science (AQA). WebOther articles where endothermic reaction is discussed: chemical reaction: Energy considerations: The opposite of endothermic is exothermic; in an exothermic reaction, energy as heat is evolved. The more general terms exoergic (energy evolved) and endoergic (energy required) are used when forms of energy other than heat are involved. WebFor an endothermic chemical reaction to proceed, the reactants must absorb energy from their environment to be converted to products. In an exothermic reaction, the energy of the products is lower than the energy of the reactants, hence is energetically downhill, shown in Figure 9.5. 2 B. Energy is given off as reactants are converted to products. how long are mini donkeys pregnant
