Chemical Changes and Structure (Higher)
This Unit covers the knowledge and understanding of controlling reaction rates and periodic trends, and strengthens the learner’s ability to make reasoned evaluations by recognising underlying patterns and principles. Learners will investigate collision theory and the use of catalysts in reactions. Learners will explore the concept of electronegativity and intra-molecular and intermolecular forces. The connection between bonding and a material’s physical properties is investigated.
