Equilibrium and temperature

What can we infer about a reaction when the value of K goes down when the temperature increases and vice verse

[hadydamaj27]

When the value of K goes down when the temperature increases, we can infer that the reaction is exothermic. If K were to increase, we could infer that it is endothermic.

[Valeria Perez 3J]

When the value of K goes up in accordance to an increase in temperature, then we know that the reaction is shifting towards the products, so heat is a "reactant" in this reaction, and it is therefore endothermic. When K goes down in accordance to a increase in temperature, we know that the reaction shifts towards the reactants, which means that heat is produced in this reaction, and therefore it is exothermic.

The relative favorability of the forward and reverse reactions at different temperatures is reflected in the change in the equilibrium constant (K) with temperature. An endothermic forward reaction tends to occur at higher temperatures when K decreases with increasing temperature, whereas an exothermic forward reaction occurs at lower temperatures when K increases with increasing temperature. These variations in K can offer significant understanding into the reaction's thermodynamics and temperature dependence.
