LeChatelier's Principle

The LeChatelier's Principle Concept Builder assesses students' ability to predict the direction that an equilibrium shifts in response to a stress or disturbance. There are a total of 54 questions in this Concept Builder. They are organized into 18 different Question Groups and spread across the three difficulty levels. Question-specific help is provided for each of the 18 situations. Questions in the same Question Group include identical types of stresses - for instance, an increase in pressure. The built-in score-keeping makes this Concept Builder a perfect candidate for a classroom activity.
