I created these notes throughout y12&13 and used them for my A level 2022 exams. I got a grade 9 in GCSE and an A* at a level. These notes were made using the CGP revision guide, edexcel textbook and class notes in order to cover everything in the course. I have also added markschemes from past paper questions and also used the markschemes to help me write the notes to ensure I used the specific words and terminology needed in order to get the marks in the exam. The notes are organised according the the subtopics from the main Edexcel textbook.

11.1 REVERSIBLE REACTIONS & DYNAMIC
EQUILIBRIUM
19 November 2021
17:52
Dynamic equilibrium - Forwards and backwards reactions occur at constant rates and
so there is no overall change.



11.2 THE EQUILIBRIUM LAW

● Homogeneous systems.
In hetrogeneous equilibrium, solids and pure liquids aren't expressed in the Kc
expression as their concentrations stay constant.

The equilibrium constant can also be calculated from experimental data.
A mixture will eventually lead to equilibrium.
● Samples can be titrated to find the equilibrium concentration.



11.3 GASEOUS EQUILIBRIA
19 November 2021
19:59
Partial pressure - Pressure that the gas would exert if it were the only gas present in
the container.
● The sum of individual partial pressures is the total pressure.

The moles of gas determines the pressure.
● Partial pressure is proportional to the concentration of gas in the mixture.
A mole fraction is the proportion of a particular gas in a gas mixture.
● Total pressure is shared between gases according to their mole fractions.
