Grade 10 Science Module: Factors Affecting the Rates of Chemical Reactions

This Self-Learning Module (SLM) is prepared so that you, our dear learners, can continue your studies and learn while at home. Activities, questions, directions, exercises, and discussions are carefully stated for you to understand each lesson.

Each SLM is composed of different parts. Each part shall guide you step-by-step as you discover and understand the lesson prepared for you.

Pre-tests are provided to measure your prior knowledge on lessons in each SLM. This will tell you if you need to proceed on completing this module or if you need to ask your facilitator or your teacher’s assistance for better understanding of the lesson. At the end of each module, you need to answer the post-test to self-check your learning. Answer keys are provided for each activity and test. We trust that you will be honest in using these.

Please use this module with care. Do not put unnecessary marks on any part of this SLM. Use a separate sheet of paper in answering the exercises and tests. And read the instructions carefully before performing each task.

Where can you find chemical reactions? Chemical reactions can be observed around us. You see a block of wood burning, an iron rusting, a metal bridge corroding, and dried leaves decaying. Some of these events happen so fast like the burning of wood. Others we can notice after a few weeks like the decaying of leaves. The corroding metal bridge may take time before we can see that there are some changes in its appearance. How fast or how slow a chemical reaction occur will vary. Some reactions are fast like burning while some are slow like rusting.

This module will provide you with information and simple activities that will help you understand the reasons behind the rates of chemical reactions.

After going through this module, you are expected to:

1. Explain how the factors affecting rates of chemical reactions are applied in food preservation and materials production, control of fire, pollution, and corrosion.

Going through this module can be a meaningful learning experience. All you need to do is make use of your time and resources efficiently.
