LeChatelier Principle 1

LeChatelier's Principle 1 models the behavior of a chemical reaction under various conditions. Variables such as pressure, temperature, concentration and volume each alter the state of a chemical equilibrium when they are modified. LeChatelier's Principle states that when stress is applied to a system at equilibrium, the system will alter to reestablish a new equilibrium. The model allows students to observe how this principle is realized for the transformation of nitrous oxide to dinitrogen tetraoxide.
