Understanding Le Chatelier's Principle

Le Chatelier's Principle is really useful when we want to know what happens to a reaction when we change the temperature. Let’s break it down simply:

1. Endothermic Reactions:

   • An endothermic reaction is when it takes in heat.
   • If we heat this type of reaction up, it will shift to the right, which means it will make more products.
   • You can think of it like the reaction is trying to soak up that added heat.

2. Exothermic Reactions:

   • An exothermic reaction is when it gives off heat.
   • If we raise the temperature of this reaction, it will shift to the left, making more reactants.
   • Imagine the reaction is trying to cool itself down.

3. Changing Concentration:

   • When we change the temperature, it can also change how much of each substance is present in the reaction.
   • This affects the equilibrium constant, which we can call ( K ).
   • Generally, higher temperatures will lower ( K ) for exothermic reactions.

Knowing how these changes work can really help when we’re doing experiments in the lab!
