Official Correct Choice:
Option B: Product side
Concept:

Le Chatelier's Principle states that a system at equilibrium will shift to counteract any applied stress.

Formula:

$$ \text{Reactants} \rightleftharpoons \text{Products} $$

Solution:

  • Removing a product from the system creates a concentration deficit on the right side of the chemical equation.


  • To counteract this loss and restore the equilibrium constant (\( K_c \)), the system speeds up the forward reaction.


  • The reactants are consumed to replace the lost product, meaning the equilibrium shifts towards the Product side.


Why other options are incorrect:

Shifting toward the reactant side would only happen if reactants were removed or products were added.
