This section covers the behaviour of pure and mixtures of ideal gases. Chemical reactions involving gases are required. Syllabus referenceStructure 1.5.1 - An ideal gas consists of moving particles with negligible volume and no intermolecular forces. All collisions between particles are considered elastic.
Guidance Tools and links Structure 1.5.2 - Real gases deviate from the ideal gas model, particularly at low temperature and high pressure.
