Rate of Reaction & Equilibrium (IGCSE/GCE O Level CHEMISTRY) 0620

Mastering Rate of Reaction and Equilibrium | IGCSE Chemistry Explained In this comprehensive IGCSE/O Level chemistry tutorial, we dive into two key concepts: the rate of reaction and chemical equilibrium. By the end of this video, you'll gain a solid understanding of how to control reaction rates and predict equilibrium shifts—critical skills for acing your exams! Understanding Rate of Reaction: We'll break down the five factors that influence the rate of a chemical reaction: Surface area of reactants: Why smaller particles increase the frequency of collisions, speeding up the reaction. Concentration: How a higher number of particles per unit volume increases the frequency of collisions, speeding up the reaction. Pressure (for gases): Why increasing pressure increases the frequency of collisions between gas particles, speeding up the reaction. Temperature: How higher temperatures give particles more energy, leading to more frequent and energetic collisions. Catalyst: How catalysts lower the activation energy, increasing the rate of reaction by allowing more particles to collide with enough energy to react. Mastering Equilibrium: Explore the two main factors that shift the position of equilibrium and affect product yield: Temperature: Learn how to predict the effect of temperature based on whether the forward reaction is endothermic or exothermic. Pressure: Discover how an increase in pressure favors the side of the reaction with fewer gas particles, increasing product yield in certain reactions. Engage with Real Exam Practice: Put your knowledge to the test with practice questions designed to help you confidently tackle questions on reaction rates and equilibrium in your IGCSE exams.
