ENDOTHERMIC AND EXOTHERMIC REACTION

Click here to watch video

This topic explains the difference between Endothermic and Exothermic Reactions. There are number of chemical reactions in Chemistry and they are divided into many sub and main reactions. Similar is the case with the endothermic and exothermic reactions in Chemistry. These release energy in the form of sound, light, cold or heat.

In simple terms, the endothermic reactions absorb energy from the surrounding that is in the form of heat. While, the exothermic reaction releases energy into the surrounding from the system.

A popular example of endothermic chemical reaction is photosynthesis. During this process, plants absorbs energy from the Sun and converts it into carbon dioxide and water into glucose and oxygen. While an example for the exothermic reaction is the table salt – it is a mixture of sodium and chlorine, which yields to table salt.

Endothermic Reactions

The endothermic process is a term that describes a reaction where the system absorbs the energy from its surrounding in the form of heat. Few examples of endothermic process is photosynthesis, evaporating liquids, melting ice, dry ice, alkanes cracking, thermal decomposition, ammonium chloride in water and much more.

Exothermic Reactions

The exothermic reaction is the opposite of an endothermic reaction. It releases energy by light or heat to its surrounding. Few examples are neutralization, burning a substance, reactions of fuels, deposition of dry ice, respiration, solution of sulfuric acid into water and much more.

Difference Between Endothermic and Exothermic Reactions

Endothermic Reaction	Exothermic Reaction
A reaction that the system absorbs energy from its surrounding in the form of heat.	A reaction that releases energy from the system in the form of heat.
The energy is absorbed from the surround into the reaction	The energy is released from the system to its environment.
Energy in the form of heat	Energy is released as heat, electricity, light or sound.
Melting ice, evaporation, cooking, gas molecules, photosynthesis are few examples	Rusting iron, settling, chemical bonds, explosions, nuclear fission are a few examples.

“Jace?"
"Yeah?"
"How did you know I had Shadowhunter blood? Was there some way you could tell?"
The elevator arrived with a final groan. Jace unlatched the gate and slid it open. The inside reminded Clary of a birdcage, all black metal and decorative bits of gilt. "I guessed," he said, latching the door behind them. "It seemed like the most likely explanation."
"You guessed? You must have been pretty sure, considering you could have killed me."
He pressed a button in the wall, and the elevator lurched into action with a vibrating groan that she felt all through the bones in her feet. "I was ninety percent sure."
"I see," Clary said.
There must have been something in her voice, because he turned to look at her. Her hand cracked across his face, a slap that rocked him back on his heels. He put a hand to his cheek, more in surprise than pain. "What the hell was that for?"
The other ten percent," she said, and they rode the rest of the way down to the street in silence.”
