AQA GCSE chemistry written questions revision notes

Some of the hardest questions for many GCSE chemistry students are the long answer written questions, explaining things like why the rate of reaction increases when you increase the temperature, and how the position of equilibrium shifts. So I’ve written a one-page set of notes for AQA that covers all these questions, fitting them onto a single page.

These notes cover:

• how temperature and concentration affect rate of reaction
• melting point of ionic, molecular and giant covalent chemicals
• equilibrium position
• conductivity

It makes chemistry so much easier for students having everything on a single page. A version with colour pictures is included.

Particularly intended for GCSE chemistry but I think it’s also pretty helpful for A-level students just starting the course who need to recap what they did last year, many will have forgotten these topics.

This set of notes was written against the current AQA GCSE science specifications. Past paper mark schemes consulted include:

ionic bonding:
4.3 from 8464/C/2H, 2018, specification reference 5.2.2.3.

giant covalent bonding:

5.1 from 8464C1H 2018, specification reference 5.2.3.1
3.4 from 8465/3H 2019, specification 4.8.1.1

simple molecular bonding and intermolecular forces:
4.4 from 8464/C/1H 2019, 5.1.2.6 and 5.2.2.4
7.1 from 84644C2H specimen, 5.2.2.4

concentration and rate:

5.5 from 8464/C/2H 2019, specification reference 5.6.1.3
