According to Le Chatelier’s principle, which statement is true?
The equilibrium constant is unchanged by temperature changes.
The equilibrium constant changes with a change in temperature.
The equilibrium constant increases with the concentration of reactants.
The equilibrium constant decreases with the concentration of products.

The equilibrium constant changes with a change in temperature.

Explanation:

Le Chatelier's principle states that if an external constrain such as a change in temperature, pressure or concentration is impossed on a chemical system in equilibrium, the equilibrium will shift so as to neutralize the effect. From the above principle, a change in temperature will result in a change in the equilibrium position as well as the equilibrium constant.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
