Equilibrium Constant Expression - Directions
Using the Equilibrium Constant Expression Concept Builder is quite simple. There are three difficulty levels. Every question in each difficulty level has the same idea. You are presented with a balanced chemical equation for a reaction and you must identify the correct equilibrium constant expression for the given equation. You do so by tapping on the region on the screen where it says "Tap here to toggle through the answer options." Each time you tap, a new answer option is displayed and a Check Answer button appears. Continue tapping until you find your preferred answer. A counter is displayed below the answer option that shows which option number you are viewing out of the five to eight options. Once you are satisfied with your choice of an answer, tap on the Check Answer button. Your answer(s) will be evaluated and your Progress Report will be updated.
Your goal is to earn "Stars" and to complete one or more difficulty levels. Stars are earned when you show success on a particular question. If you miss a question then you will have to answer two similar questions correctly before earning a star. Once you show success on all the questions for a particular difficulty level, you will earn the trophy for that difficulty level.
