Get an explanation in at most 4 sentences, plain text, that uses only the crowded-hallway analogy Ms. Ferreira used in class, with no equations and none of the terms you haven't learned yet (reaction quotient, Q, Gibbs free energy). It must answer that exact example, not explain the whole principle.","materialLabel":"Your chemistry notes (attached to your prompt automatically)","material":"AP CHEM - Unit 7 Equilibrium - Ms. Ferreira - 10/22\n\nLe Chatelier's principle: if you stress a system at equilibrium, it shifts to undo (relieve) the stress.\n\nStresses: change concentration, change pressure (gases), change temperature\n\nMs. F's analogy: equilibrium is like a school hallway between two classrooms (left room = reactants, right room = products). Students walk both ways at the same rate so each room stays the same size. If you shove extra students into one room, more people walk OUT of that room until it evens out again.\n\nExothermic reaction: gives off heat. So heat is basically a PRODUCT.\n  A + B <-> C + heat\n\nClass example she wants us to explain in words on the test:\n\"You heat up an exothermic reaction at equilibrium. Which way does it shift and why?\"\n\nWhat I don't get: why would adding heat do anything if heat isn't even a chemical??\n\nTextbook (ch 13) words we haven't covered: reaction quotient (Q), Gibbs free energy, K changes with temp (she said \"next week\")\n\nJordan in my lab group says heating ALWAYS speeds up the forward reaction so it shifts right. Not sure.\n\nQuiz Friday, lab report due Monday.","rules":[{"type":"maxSentences","max":4},{"type":"plainText"}],"mistakes":[{"title":"Not capping the length","why":"AI explains thoroughly by default and runs to two or three paragraphs.","fix":"Set a hard limit: \"At most 4 sentences.\"","checks":["maxSentences"]},{"title":"Asking about the whole principle","why":"\"Explain Le Chatelier\" gets a general overview that may never touch your exact example.","fix":"Quote the example: \"Why does heating an exothermic reaction shift it left?\"","checks":["r0"]},{"title":"Not naming the analogy","why":"The AI invents its own comparisons, which won't match what you'll write on the test.","fix":"Say: \"Use only the hallway analogy from my notes.\"","checks":["r1"]},{"title":"Letting it use new terms","why":"AI reaches for textbook vocabulary and equations you haven't learned yet.","fix":"List them: \"No equations, and don't use Q, reaction quotient or Gibbs free energy.\"","checks":["r2"]},{"title":"Forgetting where it will be read","why":"AI formats for a screen, with bold and headings that show up as stray symbols in your notes app.","fix":"Say: \"Plain text, no bold, no headings.\"","checks":["plainText"]}],"promptHints":[{"label":"Caps the number of sentences","patterns":["\\b(4|four)\\b.{0,15}sentence","sentences?
