SECTION: CHEMISTRY

MODULE: 18

Part A: Units

1. Reaction rates and reversible reactions

a. Reaction rates

b. Reversible reactions

2. Electrochemistry

a. Redox reactions

b. Displacement reactions (as redox reaction)

c. Electrochemical cell

d. Electrolysis

e. Applications

Part B: Project

Demonstrate reaction rate changes and electrochemistry concepts.

Project Title: Rate of Reaction and Electrochemistry

Objective: Observe rate changes and explain redox and electrolysis.

Project Instructions:

1. Conduct a simple reaction and change one factor to observe rate.
2. Record observations and explain the factor effect.
3. Identify a redox or displacement reaction example.
4. Describe the parts of an electrochemical cell.
5. Explain one application of electrolysis.
6. Consult your coach where necessary.

Evidence to Submit:

• Reaction rate notes and explanation.
• Redox or displacement example.
• Electrochemistry summary.

Submission

Part C: Training Others

Teach a peer about reaction rates and electrochemistry basics.

Guidance:

• Explain what changes reaction rate.
• Discuss redox and displacement reactions.
• Show how electrolysis works in simple steps.

Reflection:

• What did the learner understand well?
• What needed more explanation?
• What support do you need from your coach?

Submission

Part D: Assessment

Competency Levels:

1 = Expectations not met

2 = Partially met

3 = Satisfactorily met

4 = Excellently met

Coach assessment: Learner completes the self-assessment using the 1-4 scale. The coach prepares a short quiz or conversation (outside the system if needed) and assigns the coach score.

Self-assessment:

• Reaction rates and factors:
• Reversible reactions and redox:
• Electrochemistry and electrolysis:

Coach assessment:

• Reaction rates and factors:
• Reversible reactions and redox:
• Electrochemistry and electrolysis:
