Practice question · True or false
Le Chatelier's principle states that a system at equilibrium will shift to partially oppose any stress applied to it.
Hints
- Ask whether the system fully undoes the stress or only partly.
- A new equilibrium is reached, not the original one.
Show the answer
True
Why
The shift is partial, not total; the system reaches a new equilibrium, not the exact original state. Adding reactant shifts right; removing product shifts right; increasing T favours the endothermic direction.
