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 is applied to a system at chemical equilibrium, the system will shift in a direction that counteracts (reduces) the stress to re - establish equilibrium. "Normalizes the stress" is not the correct description as the system doesn't aim to normalize but to reduce the stress. "Increases the stress" goes against the principle as the system tries to relieve the stress. "Changes the stress" is too vague and not in line with the principle's description of the system's response (it specifically reduces the stress, not just any change).

Answer:

A. reduces the stress.
