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

Описание: 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.
