AI Concept Explainer for High School

Sofia is a junior in AP Chemistry. She can apply Le Chatelier's Principle to problems but cannot explain why it works, a gap that will cost her on the free-response section of the AP exam. She opens the concept explainer, types "Le Chatelier's Principle," and selects Expert. The explanation walks through the underlying thermodynamic reasoning: why a system in equilibrium minimizes stress by shifting the reaction equilibrium. She reads it twice and can now write a mechanistic explanation, not just apply the rule.
