Endothermic Reactions:

An endothermic reaction is a type of chemical reaction that absorbs energy from its surroundings, typically in the form of heat. This absorption of energy results in a decrease in the temperature of the surrounding environment. Here’s a detailed explanation:

Characteristics of Endothermic Reactions:

1. Energy Absorption:
   During an endothermic reaction, the system absorbs heat energy from the surroundings. This energy is required to break bonds in the reactants and form new bonds in the products. As a result, the surroundings feel cooler.
2. Temperature Change:
   The temperature of the reaction mixture typically decreases because the reaction takes in heat from the surroundings. This can be observed by placing the reaction container in a thermal environment, like a beaker of water, which will show a decrease in temperature.
3. Enthalpy Change (ΔH):
   In endothermic reactions, the enthalpy change (ΔH) is positive. This is because the energy required to break bonds in the reactants is greater than the energy released when new bonds are formed in the products.
