In this video, we discuss VBU Semester 4 MJ-7 Physical Chemistry Important Questions (Thermodynamics – Lecture 1) in a clear, systematic and exam-oriented manner. The questions solved in this lecture are very important for university examinations and are frequently asked as long-answer (derivation + theory) questions. Each derivation and principle is explained step-by-step so that students can easily understand and reproduce answers in exams. 📌 Questions Solved in This Video 🔹 Question 8 ✔ Derive the expression for entropy change of an ideal gas for: • change in temperature and volume • change in temperature and pressure ✔ Physical significance of entropy change ✔ Exam-oriented derivation method 🔹 Question 9 ✔ State Le Chatelier’s Principle ✔ Application of Le Chatelier’s principle ✔ Conditions favouring the formation of: • Ammonia (Haber process) • Nitric oxide ✔ Effect of temperature, pressure and concentration 🎯 Who Should Watch This Video? • BSc Semester 4 chemistry students • MJ-7 / Major chemistry students • VBU exam aspirants • Students revising thermodynamics important questions 📲 Join Telegram for Notes, PYQs & PDFs 👉 https://t.me/NEPBSc (get derivations, important questions, numericals & exam materials) vbu sem 4 chemistry, mj 7 chemistry important questions, thermodynamics bsc chemistry, entropy change derivation, entropy temperature volume pressure, le chatelier principle applications, ammonia formation conditions, nitric oxide formation, physical chemistry important questions, bsc chemistry thermodynamics, nep 2020 chemistry, fyugp chemistry #mj7chemistry #thermodynamics #physicalchemistry #bscchemistry #semester4 #vbu #lechatelierprinciple #entropy #nep2020 #fyugp #majorchemistry
