AQA A-level Chemistry 7405 Paper 1

7405/1 · 2 hours · 105 marks · 35.0% of the A level.

What it examines

Physical chemistry sections 3.1.1 to 3.1.4, 3.1.6 to 3.1.8 and 3.1.10 to 3.1.12, all of inorganic chemistry (section 3.2), and the practical skills that go with them.

Sections 3.1.2 to 3.1.4 and 3.1.6 of physical chemistry are examined on this paper and on Paper 2, so amount of substance, bonding, energetics and equilibria come up twice. Inorganic chemistry is on this paper and not on Paper 2.
