GCSE Chemistry - Reversible Reactions & Dynamic Equilibrium (2026/27 exams)

⭐️ Check out our website https://www.cognito.org/ ⭐️ ** WHAT'S COVERED ** 1. Reversible Reactions The difference between one-way and reversible chemical reactions. Understanding the forward and backward reactions indicated by the double arrow symbol. 2. Dynamic Equilibrium How the rates of the forward and backward reactions lead to a state of equilibrium. The definition of dynamic equilibrium: when the rates of the forward and backward reactions are equal. Why the concentrations of reactants and products remain constant at equilibrium. The necessity of a closed system for equilibrium to be established. 3. The Position of Equilibrium What it means for the position of equilibrium to lie to the left or to the right. How the position of equilibrium relates to the relative concentrations of reactants and products. An overview of how changing conditions (like temperature) can shift the position of equilibrium. 4. Energy Changes in Reversible Reactions The principle that if the forward reaction is endothermic, the backward reaction is exothermic, and vice-versa. An example using the thermal decomposition of hydrated copper sulfate. ** CHAPTERS ** 0:00 Introduction 0:19 Reversible Reactions 1:10 Dynamic Equilibrium 2:22 Position of Equilibrium 3:42 Closed Systems 4:03 Endothermic & Exothermic Reactions ** PLAYLISTS **    • KS3 Biology      • KS3 Chemistry      • GCSE Maths (9-1)      • GCSE Biology (9-1)      • GCSE Chemistry (9-1)      • GCSE Physics (9-1)      • A-Level Biology   #GCSE #Chemistry #study #revision #school #exam #AQA #OCR #Edexcel #IGCSE
