Le Chatelier’s Principle Introduction: In this experiment you will observe shifts in equilibrium systems when conditions such as concentration and temperature are changed You will explain the observed color changes of four reactions in terms of Le Chatelier’s principle Le Chatelier predicted how an equilibrium system would respond to
Le Châtelier’s Principle According to Le Châtelier’s Principle, when a system at equilibrium is subjected to a stress (a change in concentration, temperature, or pressure), the equilibrium will shift in the direction that tends to counteract the effect of the

Le Chatelier's Principle Le Chatelier's principle states that when a system in chemical equilibrium is disturbed by a change in temperature, pressure, or concentration, the system will shift in equilibrium composition in a way that tends to counteract this change of variable The three ways that affect this change in equilibrium include:
28 Le Châtelier's Principle Driving Questions Some chemical reactions perform a balancing act much like walking a tightrope If something disturbs a reaction that is in equilibrium, it needs to adjust in order to regain its balance Chemists purposefully disrupt certain chemical reactions that are in equilibrium in order to produce more products
Le Châtelier's Principle “If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or total pressure, then the equilibrium shifts to partially counteract the imposed changethe equilibrium shifts to partially counteract the imposed change ”

LeChatelier Principle
Le Châtelier's principle: Whea chemical system at equilibrium is dis- turbed, the system shifts in a direction that minimizes the disturbance In other words, a system at equilibrium tends to maintain that equilibrium—it bounces back when disturbed We can understand Le Châtelier's principle by returning to our two neighboring countries analogy Suppose the populations of Country A and Country B are at
