"According to le chateliers principle, if the equilibrium system gains heat, then it shifts in a way to absorb heat"

R+heat ----> P
R ----> P + heat
If you gain heat, don't you shift to expel heat? So, in an endothermic reaction, wouldn't you shift to products and in an exothermic reaction wouldn't you shift to reactants?

If you get extra heat in your top reaction, it will move to the right and absorb the heat.

It's kind of tricky the way they say it. I think what they meant is the R + heat ----->P reaction has to react is a way to relieve itself from that stress ie absorbing that heat.

Bump...Does anyone have anything to add about the OP question?

what do you want to know?

if it helps: I like to think of energy as another reagent. So it's like asking "what if more X ion was added?" makes it easier for me to think about it.

If you gain heat, you shift to absorb the heat, not expel it. There is no way to "expel (get rid of)" heat, you can either create it or you can absorb it. Since here you are getting extra heat, which your system does not like, it will work to absorb that heat in the form of higher energy bonds. Thus, the endothermic reaction will proceed forward, absorbing some of this excess heat, and returning the system to a more comfortable equilibrium, at the lower temperature.

You're simply replacing "absorb" in their sentence with "expel." The only way to expel heat is to absorb it. But yes, your sentence is correct, as long as you know that expelling heat actually means absorbing heat.
