le châteliers principle is best expressed by which of the following statements? choose 1 answer: a when a system at equilibrium is disturbed, the reaction shifts in the direction that restores equilibrium. b when a system at equilibrium is disturbed, the reaction rates are reversed until the system returns to equilibrium. c when a system at equilibrium is disturbed, the forward reaction rate increases to produce more product.
Answer
Brief Explanations:
Le Châtelier's Principle states that when a system at equilibrium is subjected to a change, it will shift in the direction that counter - acts the change and restores equilibrium. Option A correctly describes this. Option B is incorrect as reaction rates are not reversed. Option C is too one - sided as the shift can be in either the forward or reverse direction depending on the disturbance.
Answer:
A. When a system at equilibrium is disturbed, the reaction shifts in the direction that restores equilibrium.
