Chemical equilibrium and temperature
« on: November 25, 2016, 08:22:01 AM »
Hello.

I have a doubt regarding the temperature in chemical equilibrium.

First, every reaction is endotermic or exotermic. Being a reaction in equilibrium means that the reaction is producing reactants and products permanently. Then, the reaction is releasing energy and absorbing energy. Being in a closed system, when the reaction release energy as heat, the temperature of the system should rise. In the other hand, when the reaction absorbs energy, the temperature of the system should decrease.

In equilibrium, ¿the temperature stay constant or vary?

In different temperatures the equlibrium constants are different.
I recommend reading textbook, or even though (for the beginning) Wikipedia.

If you read carefully, I asked another thing.

It seems I got a concept wrong. In equilibrium there is no reaction anymore. Is this right?

There is no net reaction any more, unless the conditions change.

@carlitos_30
It would be of interest as to your understanding of the deference between
no net reaction
and
no reaction

Yes, thanks you. I reread the chemical equilibrium chapter in the book and it says that they keep reacting at the same rate.

And since the reaction in one direction absorbs as much heat as the other direction produces heat, the temperature remains constant.
