Changes in Temperature

[Bianca Barcelo 4I]

How does endothermic and exothermic reactions affect the way a reaction will shift to (which side does it favor)?

[Srikar_Ramshetty 1K]

Temperature is the only variable that can change the K value. If the temperature rises the products in an endothermic reaction will be favored and reactants in an exothermic reaction will be favored. Vice versa when the temperature is decreased. '

Hope this helps!

endothermic- formation of products is favored by a increase in temperature
raising the temperature of a reaction mixture at equilibrium will shift the reaction in the endothermic direction
exothermic- formation of products is favored by a decrease in temperature

since K is temp. dependent, if a rxn needs heat (endothermic) the products will be favored. if a rxn is releasing heat (exothermic) the reactants will be favored. I see it as if you need heat you need more energy to produce, and if you give off heat, you are favoring your reactants

Changing temperature changes K.

In an endothermic reaction (heat is added), products are favored.
In an exothermic reaction (heat is released), reactions are favored.

Hope that helps! (:

In an endothermic reaction ( delta T> 0) heat is absorbed so equilibrium shifts to the right. In an exothermic reaction ( delta T<0 ) , heat is released , the reaction goes towards the left.

For endothermic reactions:
If temperature increases, then the forward reaction is favored.
If temperature decreases, then the reverse reaction is favored.

For exothermic reactions:
If temperature increases, then the reverse reaction is favored.
If temperature decreases, then the forward reaction is favored.

For endothermic reactions heat is on the reactants side. For exothermic reactions, heat is on the products side. With this in mind, I just think about temperature the same way I think about concentration changes for reactants and products.

If a reaction is endothermic( absorbs energy), a temperature increase will favor the products side. If a reaction is exothermic( gives off energy), a temperature increase will favor the reactants side.

endothermic- products are favored by a increase in temperature
exothermic- products are favored by a decrease in temperature
