Question

according to le chateliers principle, a system in chemical equilibrium responds to stress by shifting the equilibrium in a direction that
○ reduces the stress.
○ normalizes the stress.
○ increases the stress.
○ changes the stress.

Explanation:

Le Chatelier's principle states that when a stress (change in conditions like concentration, temperature, pressure) is applied to a system at chemical equilibrium, the system will shift the equilibrium position in a direction that opposes or reduces the stress to re - establish equilibrium. "Normalizes", "increases" or "changes" the stress do not align with the principle's definition.

Answer:

A. reduces the stress
