2 A Local LeChatelier Principle for Optimization Problems To explain Samuelson’s original LeChatelier principle and set a context for the modern extensions, we restrict attention to the simplest form of the principle—one 1 Samuelson (1947, 1949, 1960a, 1960b, 1972)
Chemical Equilibria, LeChatelier’s Principle v010714 You are encouraged to carefully read the following sections in Tro (2nd ed ) to prepare for this experiment: Sec 14 9 (LeChatelier’s principle), pp 740 – 3 (indicators) The effect of equilibrium is everywhere in the physical world You have lots of experience with systems
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 ”
Le Châtelier's principle provides a way to predict qualitatively the direction of change of a system under an external perturbation Example from pg 4 of Lecture 20 notes: Maximizing the Yield of Nitrogen Fixation Haber-Bosch Process The Haber-Bosch process is a nitrogen fixation reaction in which ammonia (NH 3) is
Use Le Chatelier’s Principle to predict how the equilibrium concentration of the complex ion FeCl2+ will change when: a Fe(NO 3) 3 is added b Cl-is precipitated as AgCl by addition of AgNO 3 c The temperature is increased d A catalyst is added 13 96 What concentration of NH 3 is in equilibrium with 1 0 * 10-3 M N 2 and 2 0 * 10-3 M H 2 at
Unit 5, Lesson 09: Le Chatelier’s Principle, Quantitative Approach We have seen that if an equilibrium system is “stressed” by the addition or removal of a reactant or product, a change in pressure or volume, or a change in temperature, the system will shift in such a way as to reduce the effect of that stress
A Statement of Le Chatelier's Principle (very important) 1 If a change is imposed on a system at equilibrium, the position of the equilibrium will shift in a direction that tends to reduce that change B The Effect of Change in Concentration 1 If a reactant or product is added to a system at equilibrium, the system will
