An endothermic chemical reaction is a reaction that absorbs heat energy from its surroundings. In this type of reaction, the products have a higher amount of energy than the reactants. This means that energy is being taken in from the surroundings, making the surroundings cooler. An example of an endothermic reaction is the reaction between ammonium nitrate and water, commonly used in instant cold packs. When the ammonium nitrate dissolves in water, it absorbs heat from the surroundings, making the pack feel cold.
On the other hand, an exothermic chemical reaction is a reaction that releases heat energy into its surroundings. In this type of reaction, the products have a lower amount of energy than the reactants. This means that energy is being released from the reaction, making the surroundings warmer. An example of an exothermic reaction is the combustion of methane (CH4) in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). This reaction releases a large amount of heat and light energy, resulting in the production of a flame and giving off heat to the surroundings.
