Exothermic and Endothermic reactions?

Question

Hey. I was just wondering.. I know exothermic reactions release heat and have a molar heat which is<0; and endotrhermic abosorb heat and have a molar heat which is >0. Although I find this concept quite confusing as it seems to defy logic (negative for release???)

Why do exothermic reactions experience raise in temperatures while endothermic drop??

In exothermic, is the energy needed to break bonding more/less than the energy produced by bond formation? Why??

What else can you tell me to clarify this concept??

Thanks.

Answer 1

Exothermic reactions release heat into the surrounding such as water for example, and therefore the water experiences a raise in temperature.

In endothermic reactions such as ice melting for example, ice takes in the heat which leads to melting because the ice isn&#039;t as cold as it was before and because it absorbs heat from the environment, endothermic reactions experience drop in temperature.

Exothermic reactions release energy and this energy released by the bonds formed in products is greater than the energy needed to to break bonds in reactants.
