Question

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 change

The 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 1

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.
