Chapter 7: Rate of Reaction
What you need to learn in this chapter
In this chapter, we will be learning about the rate of reaction in chemistry. We will start by classifying fast and slow reactions that occur in our daily lives and understanding the meaning of the rate of reaction.
Next, we will investigate the factors that affect the rate of reaction through experiments, including the size of reactants, concentration, temperature, and the use of catalysts. We will also explore the application of the rate of reaction in daily life with examples.
Lastly, we will learn about the collision theory and how it explains the activation energy using real-life examples.
