The Le- Chatlier principle states that ____(a) No reaction is reversible(b) All reactions are reversible at high temperatures(c) A system experiencing disturbance shifts direction of equilibrium to nullify the change(d) A system experiencing disturbance does not shift direction of equilibrium to nullify the changeThe question was posed to me by my college professor while I was bunking the class.This intriguing question comes from Temperature & Pressure Effects in section Complex Flow Patterns, Temperature and Pressure Effects of Chemical Reaction Engineering

Answer» CORRECT option is (c) A system experiencing disturbance shifts direction of equilibrium to nullify the change

The BEST explanation: For a reversible reaction, any disturbance in the form of variation in TEMPERATURE, PRESSURE or concentration affects the equilibrium state. The equilibrium shifts in a direction such that the effect is COUNTERACTED.
