IB Chemistry practice questions, by topic
Eggzams has 1,554 original IB Chemistry questions for IB Diploma Programme, organised into 23 topics. Topics include S1.1 Introduction to the particulate nature of matter, S1.2 The nuclear atom, S1.3 Electron configurations, S1.4 Counting particles by mass: the mole and S1.5 Ideal gases. Every question has an explanation after you answer, so a wrong answer becomes a mini-lesson.

Here is the kind of question you will get, with the explanation that follows every answer. These are free in the app.
IB Chemistry · R1.4 Entropy and spontaneity (HL)
A reaction that produces more moles of gas than it consumes generally involves:
- An entropy change that cannot be predicted from mole changes
- A decrease in entropy
- An increase in entropy
- No change in entropy at all
Gas particles have much greater freedom of movement (and therefore more possible arrangements) than particles in a liquid or solid, so an increase in the number of moles of gas generally corresponds to an increase in entropy.
IB Chemistry · S2.3 The metallic model
Which of these metals has the highest melting point: sodium, magnesium or aluminium?
- Sodium
- Magnesium
- They are equal
- Aluminium
Aluminium has three delocalised electrons per atom and a small, highly charged ion, so its metallic bonding is the strongest.
IB Chemistry · R2.2 How fast? The rate of chemical change
The activation energy of a reaction is defined as:
- The energy required to completely separate all reactant particles
- The total energy released by a reaction
- The exact temperature at which a reaction begins
- The minimum energy required for a successful collision to result in reaction
Activation energy is the minimum energy that colliding particles must possess in order for a reaction to occur successfully.
