In a sample tutorial on Le Chatelier's principle, students are introduced to the definition of equilibrium, reactants, and products. They are encouraged to solve questions related to chemical equilibrium by adding reactant to a chemical reaction which tends to cause more product to form. In section five, experiment in chemical equilibrium, students are provided with equilibrium experiment. After the tutorial on equilibrium positions and discussion about how best use this experiment to explore the concept of equilibrium, students investigate the reaction of nitrogen and hydrogen to produce ammonia. With the help of computer simulation, students observe the effect of the addition of either reactants or products into the reaction vessels to check Le Chatelier's principle.
Additional features includes a vocabulary review and review problems.
Selecting vocabulary review enables students to test their knowledge of a topic's key terms by matching vocabulary words with their provided definitions. Review questions leads to a presentation of problems included in the tutorial lessons from that section of the disk, as well as additional problems on the topic. Whenever students are stuck on a problem, upon using question mark, they can get the correct answer with background information. ENC does NOT distribute this resource.
