GCSE Chemistry - Exothermic and Endothermic Reactions #43

The video tutorial explains exothermic and endothermic reactions, focusing on how energy is stored in chemical bonds and represented in reaction profiles. It discusses the importance of activation energy, illustrating how it affects the initiation of reactions. Examples of exothermic reactions, such as combustion, and endothermic reactions, like the breakdown of calcium carbonate, are provided. The tutorial also covers how to draw reaction profiles, highlighting the energy changes and activation energy involved.

How do reaction profiles differ for endothermic reactions compared to exothermic reactions?

What happens to the temperature of the surroundings during an exothermic reaction?

Provide an example of an endothermic reaction and explain the energy changes that occur.
