Thermodynamics Part-8 | Criteria for Spontaneity & Numerical |NEB Class 12 Chemistry

In this video, we discuss Part 8 of Thermodynamics: Criteria for Spontaneity. You will clearly understand how to determine whether a process is spontaneous, non-spontaneous, or at equilibrium using Gibbs Free Energy, Entropy, and Enthalpy. Topics covered in this video: • Meaning of spontaneity in thermodynamics • Conditions for spontaneity using Gibbs free energy (ΔG) • Role of entropy change (ΔS) and enthalpy change (ΔH) • Temperature-dependent spontaneity • Relationship between ΔG, ΔH, and TΔS • Shortcut rules for exam numericals • Complete numerical problems with step-by-step solutions This lesson is extremely useful for Class 12 NEB students, IOE entrance aspirants, engineering students, and anyone studying thermodynamics in chemistry. Learn with IRB and master one of the most important concepts of chemical thermodynamics. --- 🔥 Hashtags (SEO Boost + Your Name Included) #Thermodynamics #SecondLawOfThermodynamics #CriteriaForSpontaneity #GibbsFreeEnergy #FreeEnergyChange #SpontaneousProcess #ThermoNumericals #ChemicalThermodynamics #EntropyChange #EnthalpyChange #NEBClass12 #IOEEntrance #EngineeringThermodynamics #ScienceNotes #PhysicsClass12 #StudyWithPrabin #EngineeringNotesNepal #PrabinBhandari
