In both endothermic and exothermic reactions
WebThis is a useful class experiment to introduce energy changes in chemical reactions, suitable for 11–14 and 14–16 year olds. Students measure the temperature changes in different reactions taking place in a polystyrene cup, classifying the reactions as exothermic or endothermic. The experiments can also be used to revise different types of ... WebAug 22, 2024 · A chemical reaction in which the heat is absorbed is called an endothermic reaction. This reaction causes a fall in temperature. Exothermic reactions cannot occur spontaneously. For this reaction to occur, external energy must be supplied. Examples of Endothermic Reactions Example 1: Photosynthesis

WebIf a reaction is exothermic. in one direction, it will be endothermic. in the other direction. The same amount of energy is transferred in both the forwards and reverse reaction. WebOption D: Incorrect. Since the forward reaction is exothermic, it has a lower activation energy than the reverse reaction. Students should note that while an increase in temperature will favour the endothermic reaction in an equilibrium system it increases the rate of both endothermic and exothermic reactions.
WebEndothermic and exothermic reactions are frequently seen in everyday phenomena. Examples of endothermic reactions: Photosynthesis: As a tree grows, it absorbs energy …
