Enthalpy Changes in Chemical Reactions; This lesson explores how chemical reactions involve energy changes that can be exo or endothermic.

24 € /h

Lesson Plan: Enthalpy Changes in Chemical Reactions
Grade/Level: Secondary / IGCSE / AS level
Duration: 60 minutes
Topic: Enthalpy Changes in Reactions
Lesson Objectives
By the end of the lesson, students should be able to:
1. Understand that chemical reactions are accompanied by enthalpy changes, which can be exothermic or endothermic.
2. Construct and interpret reaction pathway diagrams, showing enthalpy change and activation energy.
3. Define and use key terms: standard conditions (⦵), enthalpy change of reaction (ΔHr⦵), formation (ΔHf⦵), combustion (ΔHc⦵), and neutralisation (ΔHneut⦵).
Lesson Breakdown (60 minutes)
1. Introduction (5 minutes)
Begin with a real-life hook:
Ask: “Why does burning wood release heat, but dissolving ammonium nitrate in water feels cold?”
Link to lesson: These are examples of exothermic and endothermic reactions.
2. Theory: Enthalpy Changes (10 minutes)
Define enthalpy (H): The heat content of a system at constant pressure.
Define enthalpy change (ΔH): Heat energy transferred during a reaction at constant pressure.
Distinguish:
Exothermic reaction: ΔH is negative (heat released).
Endothermic reaction: ΔH is positive (heat absorbed).
Give simple examples:
Exothermic → combustion of methane.
Endothermic → thermal decomposition of calcium carbonate.
3. Reaction Pathway Diagrams (15 minutes)
Draw and explain two diagrams:
Exothermic pathway: Products lower in energy than reactants, ΔH negative.
Endothermic pathway: Products higher in energy than reactants, ΔH positive.
Introduce activation energy (Ea):Minimum energy needed for reaction to occur.
Label diagrams clearly:
Reactants → peak (activation energy) → products.
Highlight ΔH and Ea.
4. Standard Conditions and Key Enthalpy Terms (15 minutes)
Explain standard conditions (⦵):

298 K (25°C), 101 kPa pressure, substances in standard states.
Define and discuss:
Standard enthalpy change of reaction (ΔHr⦵): Heat change when reaction occurs in molar quantities under standard conditions.
Standard enthalpy of formation (ΔHf⦵): Heat change when 1 mole of compound is formed from its elements in their standard states.
Standard enthalpy of combustion (ΔHc⦵):Heat change when 1 mole of substance is completely burnt in oxygen under standard conditions.
Standard enthalpy of neutralisation (ΔHneut⦵): Heat change when an acid and alkali react to form 1 mole of water under standard conditions.
Use simple examples for each (e.g., combustion of methane, formation of H2O, neutralisation of HCl with NaOH).

5. Guided Practice / Mini Activity (10 minutes)
Students sketch their own reaction pathway diagrams (exothermic and endothermic).
Label ΔH and Ea.
Pair discussion: “Why do we still need activation energy even for exothermic reactions?”

6. Exercise (Homework / Classwork) (5 minutes)
Answer the following questions:
1. State whether each reaction is exothermic or endothermic:
a) Burning propane gas in oxygen.
b) Photosynthesis in plants.
c) Dissolving anhydrous copper(II) sulfate in water.

2. On a reaction pathway diagram:

Show ΔH and Ea for an endothermic reaction.

3. Define the following terms and give one example each:
a) Standard enthalpy of formation (ΔHf⦵)
b) Standard enthalpy of combustion (ΔHc⦵)
c) Standard enthalpy of neutralisation (ΔHneut⦵)

4. Under standard conditions, the enthalpy of combustion of methane is –890 kJ mol−1.

I am an interactive teacher of 5 years experience. My way of teaching is friendly and open, but clear and direct. I use lots of materials and interactive simulations and conceptual learning where possible. My abilities in education are incredibly strong and getting better every time I tutor. Given the previous situation with Covid. Online teaching has become second nature and I am happy to help your learn online as well.

Teaching methodology:
In order to teach a student effectively, it cannot simply be a matter of taking notes or going over the same material again and again. Students need time to connect concepts by approaching subjects from many angles. It takes practice and skill to make learning in a classroom interesting. I have been developing those skills over many years and continue to try and do so as I teach and learn myself!

My name is Arjen. I give tutoring and exam training in math and physics for upper secondary education (Dutch HAVO/VWO, IB, or other similar programmes). With a completed degree in Aerospace Engineering, I help students not only with solving problems, but especially with understanding the “why” behind the theory.

I start with a short diagnosis: where is the real difficulty? Based on this, I create a personal learning plan that I share with the student. In this way we work in a focused way on those areas where most is to be gained. During the sessions, the focus is on recognizing structure and analyzing problems step by step, so that students become more independent and their confidence gets a boost.

In my explanations, I regularly use examples from technology and engineering. By linking abstract theory to real applications, it becomes clearer where the mathematics or physics comes from and what it is needed for, and things often suddenly “click”.

I can give lessons both at home and via an online connection. In the latter case, I do this using a tablet, allowing you to follow my explanations and examples live on your screen.

After the the lessons, I create personal practice exercises when needed, tailored to the student’s level and learning goals. In this way, we work not only towards better results in the short term, but also towards a strong foundation for future studies.
