Reaction Mechanism & Rate Determining Step | FSc 1st Year Chemistry In this lecture, we will study reaction mechanism and understand how a chemical reaction takes place through a series of elementary steps at the molecular level. 🔹 Reaction Mechanism: A detailed step-by-step description of how a chemical reaction occurs at the molecular level to yield the products is called a reaction mechanism. 🔹 Elementary Steps: We will understand how an overall reaction can occur through several individual elementary steps. 🔹 Reaction Intermediate: A species that is formed in one step of a reaction mechanism and consumed in a subsequent step is called a reaction intermediate. 🔹 Rate Determining Step: The slowest step in a reaction mechanism that controls the overall rate of the reaction is called the rate determining step. 🧪 Example discussed: NO₂ + F₂ → 2NO₂F We will learn how experimental evidence is used to determine the mechanism and identify which elementary step is the rate-determining step. 🎓 Level: FSc 1st Year Chemistry 📚 Chapter: Chemical Kinetics 🧪 Topic: Reaction Mechanism & Rate Determining Step Explore Chemistry with Awais — Simple Explanation + Real Examples. #FScChemistry #1stYearChemistry #ChemicalKinetics #ReactionMechanism #RateDeterminingStep #ReactionIntermediate #ElementarySteps #ExploreChemistryWithAwais
