Here's why:
* Le Chatelier's Principle: This principle states that if a change of condition is applied to a system at equilibrium, the system will shift in a direction that relieves the stress.
* Stress: Removing a product is a stress on the system.
* Relieving the Stress: The system will try to replace the removed product by shifting the equilibrium to favor the forward reaction (reactants to products).
Example:
Imagine a simple reversible reaction:
A + B ⇌ C + D
If product C is removed, the system will shift to the right, producing more C and D to compensate.
Important Considerations:
* Equilibrium: This principle applies to reactions at equilibrium. If the reaction hasn't reached equilibrium yet, the removal of a product may simply slow down the overall reaction rate.
* Reversibility: The reaction must be reversible for Le Chatelier's Principle to apply.
* Other Factors: Other factors like temperature, pressure, and catalysts can also influence the reaction equilibrium.
