Study Plan

1
Day 1–2

Learn the Theory

Read the textbook chapter carefully. Note down definitions, formulas and key ideas. Focus on: 1. System, Surroundings, and Types of Systems, 2. Exothermic and Endothermic Reactions, 3. First Law of Thermodynamics and Internal Energy.

2
Day 3

Practise

Solve the textbook exercises and extra practice questions. There are 46 questions available for this chapter.

3
Day 4

Revise & Test

Revise key points without looking at your notes. Take a practice quiz and mark weak areas for another pass.

Day 7

Spaced Revision

Come back to Chemical Thermodynamics after a week. Use flashcards for quick recall and try past exam questions on this chapter.

What to Focus On

  • System: part under study; Surroundings: rest of the universe
  • Isolated system: no exchange of matter or energy
  • Closed system: exchanges energy but not matter
  • Exothermic: heat is released (ΔH < 0)
  • Endothermic: heat is absorbed (ΔH > 0)
  • Exothermic feels hot; endothermic feels cold
  • ΔH includes sign: negative for exothermic, positive for endothermic
  • States of matter must be specified
  • ΔH is proportional to moles involved

Common Mistakes to Avoid

ΔH and ΔU are always the same for all reactions.

Exothermic means the reaction is fast, and endothermic means it's slow.

ΔH is the heat content of a substance.
