Question

Write a note on Endothermic Reaction
​

Answer 1

Answer:

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. ... Physical processes can be endothermic as well – Ice cubes absorb heat energy from their surroundings and melt to form liquid water (no chemical bonds are broken or formed

Answer 2

Answer:

Hi mate here is your answer.

Explanation:

Exothermic reactionIn an exothermic reaction, the total energy of the products is less than the total energy of the reactants. Therefore, the change in enthalpy is negative, and heat is released to the surroundings.

Endothermic reaction are reaction that require external energy, usually in the form of heat, for the reaction to proceed. Since endothermic reactions draw in heat from their surroundings, they tend to cause their environments to cool down. They are also generally non-spontaneous, since endothermic reactions yield products that are higher in energy than the reactants. As such, the change in enthalpy for an endothermic reaction is always positive. In order to melt the ice cube, heat is required, so the process is endothermic.
