BIOMOLECULES AND ENZYMES

Detailed explanation-1: -An exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction.

Detailed explanation-2: -An exothermic process results when heat energy is released, decreasing the internal energy of the system. If you touch a container that holds an exothermic process, it will feel warm or hot to the touch. One example of an exothermic reaction is the hot pack you made with sodium carbonate.

Detailed explanation-3: -Exothermic Reactions Heat is released by the reaction to surroundings; surroundings feel hot. The bonds broken in the reactants are stronger than the bonds formed in the products. The bonds formed in the products are stronger than the bonds broken in the reactants.

Detailed explanation-4: -An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

Detailed explanation-5: -In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
