Chemical Reactions Made Simple | Reaction Rates, Collision Theory & Activation Energy

Why does food spoil faster in warm conditions? Why do some chemical reactions happen almost instantly while others take much longer? Understanding reaction rates helps us make sense of changes happening around us every day. In this lesson, Effiong Praise Edet breaks down chemical reactions in clear, simple language, helping you understand the ideas behind the definitions and formulas. You will learn: • What a chemical reaction is • How to identify reactants and products • The difference between reaction time and reaction rate • Collision theory and effective collisions • What activation energy means • How temperature, concentration, pressure, surface area and catalysts affect reaction rates Whether you are learning these topics for the first time or revising for an examination, this lesson will help you build a stronger foundation in chemistry. Suitable for SS2 students and learners preparing for WAEC, NECO, UTME and Cambridge IGCSE. 💬 Your turn: Why does keeping food in a refrigerator slow down spoilage? Explain your answer in the comments using what you have learned. Subscribe to Next-Gen Scholars Academy for more lessons in Chemistry, Physics and Mathematics.
