According to Le Chatelier's principle, what happens when equilibrium is disturbed by the addition of a reactant or product?

Options

  1. AThe reaction shifts in the reverse direction.
  2. BThe concentration stress of the added substance is relieved by net reaction in the direction that consumes it.
  3. CThe reaction comes to a complete stop.
  4. DThe concentration stress of the added substance is relieved by net reaction in the direction that replenishes

Correct answer

B. The concentration stress of the added substance is relieved by net reaction in the direction that consumes it.

Step-by-step solution

Le Chatelier's principle predicts that when a reactant or product is added, the equilibrium shifts in the direction that consumes the added substance.
