Welcome to the complete revision guide for Physical Chemistry for the JAC Board Class 12 Exam 2026! In this video, we’ll cover high-yield topics, chapter-wise must-know points, and exam-oriented questions that will help you score better in your board chemistry paper. ✍️ 👇 Watch till the end for bonus tips on how to prepare, revise, and solve questions quickly! 👇 🔥 IMPORTANT PHYSICAL CHEMISTRY TOPICS (JAC Board 2026) These topics are frequently asked in board exams and are crucial for revision: 📌 1. Solutions • Definitions: Molarity, Molality, Normality, Mole fraction • Raoult’s Law (Ideal & Non-Ideal solutions) • Colligative properties: Relative lowering of vapor pressure (RLT), Elevation in boiling point, Depression in freezing point, Osmotic pressure • Numerical problems on colligative properties and calculations with concentration terms � Filo 📌 2. Electrochemistry • Conductance & Kohlrausch’s Law • Electrolytic & Galvanic Cells • Nernst Equation & EMF calculation • Electrochemical series, Batteries & Fuel cells � Filo 📌 3. Chemical Kinetics • Rate law, Order & Molecularity • Zero, First & Second order reactions • Integrated rate equations and graphs � Filo 📌 4. Ionic & Chemical Equilibrium • Dissociation equilibrium constant for weak acids • Le Chatelier’s principle and factors affecting equilibrium � Filo 🧠 EXAM-ORIENTED QUESTIONS YOU SHOULD PRACTICE Here are sample questions that often appear or are predicted for boards: 1️⃣ Define molarity, molality and normality. How are they related? � 2️⃣ State and explain Raoult’s law with an example. � 3️⃣ Derive the integrated rate law for a first-order reaction and solve a numerical. � 4️⃣ Calculate the molar mass of a solute using freezing-point depression data. � 5️⃣ Explain ionic equilibrium and write the expression for the dissociation constant of a weak acid. � 👉 Besides long-answer questions, make sure to solve MCQs and short-answer types as per the latest pattern. You can find many objective practice sets online tailored to JAC board 2026. � JacUpdate 📌 BOARD PATTERN & SOLUTION PRACTICE 📝 JAC Chemistry papers include a mix of: ✔ Objective (MCQs) ✔ Short Answer ✔ Long Answer questions ✔ Numericals from physical chemistry topics � JacUpdate Practicing model papers and previous year questions helps you understand the question style and scoring pattern. Official model papers are available for download online. � अगलासेम 🎓 PREPARATION TIPS TO BOOST YOUR SCORE ✅ Understand basic concepts before solving numericals. ✅ Learn all formulae and their applications. ✅ Revise regularly instead of last-minute cramming. ✅ Attempt at least 5–10 sample papers under timed conditions. ✅ Focus more on Physical Chemistry numericals—they are often scoring. #jacboardexam2026 #jacboard2026 #chemistry #chemistrybyshashibhushan
