AIt returns by counteracting the disturbance
BIt returns by amplifying the disturbance made
CIt stays fixed regardless of any disturbance
DIt shifts always toward the product side here
Answer & Solution
Correct answer: A. It returns by counteracting the disturbance
1. A disturbance pushes the reaction quotient away from the equilibrium constant.
2. The system responds by shifting in the direction that opposes the change made to it.
3. That shift restores the quotient to the value of the equilibrium constant.
4. Amplifying the disturbance would drive the quotient further from the constant.
