Equilibrium Constants: When decreasing the temperature of an endothermic reaction; the constant (K) value decreases or increases? In my book the answer states "increase the value of the constant as the reaction is endothermic. But my notes states that "when temperature increases, the K value increases for endothermic reactions." So, doesn't the K value decrease when the temperature decreases?

    We should revisit Le Chatelier's principle.

    when temperate decreases in an endothermic reaction the equilibrium shifts to the left i think

    My notes say: "Increase temp, K decreases in exothermic rx, K increases in endothermic rx.

    yeah.. but this is decreases; so does it go the opposite?

    "Decreases temp, K down in exothermic, K up in endothermic rx"

    why does the constant increases when the temperature decreases? and when the temperature increases the constant still increases..?
