What is Le Chatelier’s Principle?
Le Chatelier’s Principle states that,
“When a system in chemical equilibrium is disturbed by a change of a factor that can affect the chemical equilibrium such as temperature, pressure, or concentration, the system shifts in equilibrium composition in a way that tends to counteract this change of variable/factor.”
