Chemistry IBDP is one of the six group 4 Sciences of the IB curriculum. The IBDP Chemistry program explores the three important aspects of chemistry: Physical, Organic, and Inorganic chemistry. The program requires the student to take a look at the qualitative and quantitative aspects of each of the sections using a range of techniques.

These techniques range from informative theoretical knowledge to practical applications in the lab and the real world. This holistic approach allows students to learn in a variety of methods including but not limited to exploration, discovery, gathering and interpreting data, analysing outcomes, and giving feedback. The IBO’s special attention to criteria ensures that the student can interconnect the subjects they have chosen and be able to apply them in real life.

In this chapter of IBDP Chemistry, we take an in-depth look at Chemical Equilibrium, and get a more realistic idea of how reactions may occur in real time. The chapter can be divided into two sections, both of which are covered in a comprehensive manner in our notes. We begin by introducing Chemical equilibrium, the types of system that one may encounter and their effect on equilibrium. We also look at different Concentration-Time and Rate-Time graphs and learn how you may derive the point of equilibrium from each.

We then discuss the equilibrium law and the equilibrium constant Kc and how to effectively use them to answer qualitative questions. Following that we have the factors that affect position of equilibrium and the relationship between the reaction quotient and equilibrium constant. As a part of the HL syllabus we continue with how quantitative data may be used to calculate the Equilibrium constant. Finally, we end with discussing the impact of equilibrium constant and Gibbs free energy and using them to identify the spontaneity of a reaction.

At the end of this chapter, we can expect the students to have an understanding of chemical equilibrium, the factors that affect it and the outcomes all of which help them throughout their IBDP career and beyond.
