Energetics – A/L Chemistry Complete Masterclass (Sinhala Medium)

✔ Lifetime access ✔ 15+ hours of video lessons ✔ Full A/L syllabus coverage
✔ Theory + Practice Problems + Answering guide ✔ Sinhala medium

This course provides a complete step-by-step explanation of Energetics for A/L Chemistry in the Sinhala medium.

Energetics is one of the most important and high-scoring lessons in the A/L Chemistry syllabus. Many students struggle to clearly understand enthalpy changes, bond energy calculations, Hess’s Law, enthalpy cycles, and solving structured numerical problems. Concepts such as standard enthalpy of formation, combustion, and neutralization often become confusing without proper guidance, especially when interpreting energy level diagrams and applying sign conventions correctly.

This course is designed to help you understand the concepts clearly, solve problems confidently, and answer exam questions correctly.

In this masterclass, you will learn:

✔ Fundamentals of energy changes in chemical reactions
✔ Exothermic and endothermic reactions
✔ Standard enthalpy changes (formation, combustion, neutralization)
✔ Drawing and interpreting energy level diagrams
✔ Bond enthalpy calculations
✔ Hess’s Law and enthalpy cycles
✔ Lattice enthalpy and Born–Haber cycles
✔ Solving structured numerical problems step-by-step
✔ Applying correct sign conventions confidently
✔ Exam techniques for structured and essay questions

This course is ideal for:

• A/L 2026 students
• A/L 2027 students
• Students repeating the A/L exam
• Students who find Energetics difficult
• Students aiming for A or B grades

Resources included

✔ Complete video lesson series
✔ Numerical problem-solving sessions
✔ Practice questions and discussions
✔ Lifetime access to materials
✔ Printed notebook provided for the course

Course duration

15+ hours of video lessons

Why this course is important

Most A/L students try to memorize Energetics without really understanding the core concepts.

This leads to:

• Confusion with energy level diagrams
• Mistakes with sign conventions (+/− ΔH)
• Difficulty applying Hess’s Law correctly
• Losing marks in structured and essay questions
• Fear of Born–Haber cycles and bond energy calculations

In this course, every concept is explained from basic to advanced level, so you can confidently answer any Energetics question in the exam.

If you attended a physical tuition class covering the full Energetics lesson, it would cost more than Rs 20,000.
