adding heat

Postby Agustina Santa Cruz 2F » Sun Jan 10, 2021 7:54 pm

Why is heating endothermic reactions more favorable?

Endothermic reactions absorb heat from the surrounding environment. So if heat is added, then there is a lower activation energy for the reaction to occur.

Increasing temp. will move the reaction towards the endothermic side whilst decreasing temp will move the reaction toward the exothermic side.

For endothermic reactions, energy in the form of heat is required to carry out the reaction. Therefore, adding heat favors the formation of the products. For exothermic reactions, the opposite is true, where adding heat favors the formation of the reactants. Exothermic reactions give off heat as the product is formed.

In exothermic reactions, you can treat heat as a product and in endothermic reactions you can treat heat as a reactant.

Endothermic reactions require heat in order to occur so adding heat would lower the activation energy and cause the reaction to occur faster.

Adding heat allows the activation energy to lower, thus resulting in a quicker reaction.

Since endothermic reactions require heat to occur, increasing temperature will aid in meeting the activation energy.

When heat is added to an endothermic reaction it favors the products because heat is required to form product.

Endothermic reactions need heat, while exothermic reactions give off heat. So if we add heat to an endothermic reaction, it promotes product formation. The opposite is true for exothermic reactions, since heating favors reactant formation.

Along with what all the others have mentioned, you can also think about this problem in terms of LeChatlier's principle. The external environment has more heat than it did previously, so to minimize the effect of that change, the reaction will use up the heat and try its best to restore the external temperature to what it was originally.

Hi! An endothermic reaction means that it requires energy. By increasing the temperature of the reaction environment, we are helping the reactants to overcome the activation energy so the equilibrium will shift to the product side.

Hope it helps!

I learned a great trick in a workshop. So if you pretend your hands are a scale, right hand products, left hand reactant, when you add heat to your right hand it will drop because it is "heavier" so you have to move left to go back to equilibrium. It works the opposite way too. I use this trick to find out which direction the reaction will proceed during Le Chateliers rule.

endothermic : heating up, shifts right, cooling down, shifts left
exothermic: hating up, shifts left, cooling down, shifts right.

Endothermic reactions require heat so adding heat can cause it to overcome the activation energy. The equilibrium would then shift towards the left or to the products' side.

Endothermic reactions require heat to occur so if you makes the surrounding environment hotter, the reaction will become favored and create more product:)

It is favorable because endothermic reactions require heat to take place and when you add heat they are able to reach the activation energy to start the reaction more easily.
