what is the significance of le châtelier's principle when used in industrial fields?

1) scientists know that reactions at chemical equilibrium will have consistent reaction rates if the intensity of external factors is steadily increased, so scientists can use external factors to manipulate these chemical reactions into producing specific results.

2) scientists know that reactions at chemical equilibrium will shift to regain equilibrium if left in the same external conditions long enough, so scientists can stabilize these chemical reactions' environments in order to produce specific results.

3) scientists know that reactions at chemical equilibrium will have consistent reaction rates despite any change in external conditions, so scientists can depend on these chemical reactions to always produce the same specific results.

4) scientists know that reactions at chemical equilibrium will shift to regain equilibrium when affected by external factors, so scientists can use external factors to manipulate these chemical reactions into producing specific results.
