Examining Board: AQA
Next Examination Period: May / June 2019
Exam Specification Code: 7404 (2016 Specification)
Coursework Element: No
Practical Element: No

AQA A Levels are available for study anywhere in the world. Examinations must be taken in a registered UK exam centre. It is recommended students check with UK examining centres that the chosen exam is available.

 

Introduction

Chemistry is an impressive subject to have on a CV – highly respected by universities and employers alike it shows a depth of learning that requires numerous skills of its students; maths, scientific reasoning, written and spoken communication and practicality among many others. It is for this reason that Chemistry is considered a highly academic subject that keeps many of life’s “doors” open to you.

Entry Requirements

Although the AS Level Chemistry AQA programmes build on the course content of GCSE, it is not necessary to have this qualification before undertaking an AS Level. However, in order to meet the demands of the course, it is recommended that candidates have literacy and communication skills equivalent to C or higher at GCSE. Please note that full tutor support is still provided throughout your course duration.

All students must be 16 years of age or above.

AS Chemistry AQA Course Duration

1 year.

Awarding Body

AQA

AQA A Levels are available for study anywhere in the world. Examinations must be taken in a registered UK exam centre. It is recommended students check with UK examining centres that the chosen exam is available.

Examination Information

Students are required to arrange and pay for their AS Chemistry AQA examinations and manage the course work element if the subject requires this. Students must check the relevant examination board website for further information and final examination sitting dates for the specification.

All examinations are held during the May / June exam period of every year.

Course Content

The full AS consists of 3 units of content:

AS Chemistry AQA Unit 1 Physical chemistry

3.1.1 Atomic structure
3.1.2 Amount of substance
3.1.3 Bonding
3.1.4 Energetics
3.1.5 Kinetics
3.1.6 Chemical equilibria, Le Chatelier’s principle and Kc
3.1.7 Oxidation, reduction and redox equations

The opening unit begins by looking at the atom, the building blocks of chemistry and considers how the atom is made up and how this impacts the chemistry of the molecules they form.  We then look at concentrations of solutions and the concept of the ‘mole’ as an amount of substance. The unit continues on to look at how atoms bind together using different types of bonding to form molecules and how the type of bonding influences the properties of a given compound. Energetics covers the energy transfers involved in chemical reactions and we investigate the requirements for a chemical reaction to successfully occur. The kinetics topic in the A-Level course show the student how the Maxwell-Boltzmann distribution and collision theory are key in the creation of models in chemistry and how they account for the different effects that changing variables can have on the rate of a reaction before the unit finishes off by looking at equilibrium reactions can go in both directions and investigates ways in which we can control the reaction, and finally, redox reactions, types of reactions that involve the loss and gain of electrons.

AS Chemistry AQA Unit 2 Inorganic chemistry

3.2.1 Periodicity
3.2.2 Group 2, the alkaline earth metals
3.2.3 Group 7(17), the halogens

Unit 2 concentrates on the chemistry of inorganic compounds (those not generally involved in living things and do not contain the element, carbon). In this unit, we look at the periodic table and some of the key families of elements within it.

AS Chemistry AQA Unit 3 Organic chemistry

3.3.1 Introduction to organic chemistry
3.3.2 Alkanes
3.3.3 Halogenoalkanes
3.3.4 Alkenes
3.3.5 Alcohols
3.3.6 Organic analysis

Unit 3 introduces the organic compounds all of which share in common the elements carbon, hydrogen and often oxygen or nitrogen. The unit opens by introducing some common ideas in organic chemistry including how to name an organic compound based on its constituent elements and the coordination of these elements within the molecule. We then look at four particular groups of organic compounds, before discovering ways in which we can analyse organic compounds to identify them.
