1. Introduction
In Chemical Part 4, you will learn more about the complexities of chemical reactions. To fully understand the concepts discussed in this part, it is important to build on the knowledge gained in previous parts.
2. Chemical Reactivity
The reactivity a substance is a function of its structure, bonding and electronic configuration. In Chemical Part 4, you will learn how these factors affect the rate of reactions and their intensity. We examine various catalysts and reaction mechanisms that facilitate chemical transformations.
Reaction Rates 2.1
Understanding reaction rates is essential for optimizing industrial processes, and creating efficient chemical systems. In this section we explore factors that affect reaction rates and the importance of activation energy. We examine concepts such as the collision theory, rate equations and transition state theory.
Catalysts
Catalysts are used in many industries to accelerate chemical reactions. They do this without being consumed. We discuss the mechanisms that catalysts work, their types and their applications. We shed light on important concepts such as catalytic cycles, enzyme catalysis, etc.
3. Thermodynamics
Thermodynamics helps predict the direction and feasibility for chemical reactions. In this section, we explore the laws of thermodynamics to better understand energy changes that occur during chemical transformations. We discuss Gibbs free energies, Gibbs entropy and equilibrium.
Entropy and Free Energies
Entropy is a measure of disorder or randomness in a system. Free energy, on the other hand, determines the spontaneity and spontaneity of the reaction. We examine here the relationship between entropy, free energy, and how they influence the direction of chemical reaction. We also discuss the concept of balance and its importance.
Thermodynamic stability
Thermodynamic stabilty is the tendency for a system to reach it’s lowest energy state. We examine the factors that influence stability, including bond strength and resonance. We also explore concepts such as reaction spontaneity and endothermic and non-endothermic reactions.
4. Kinetics
Kinetics is concerned with the speed of chemical reactions and the factors that affect their rates. This section explores reaction mechanisms, rate laws, rate constants and reaction orders. We also examine the effect of temperature on reaction rates, and the concept activation energy.
Rate Law Expressions
Rate laws describe the relationship between reactant concentrations, and the rate of chemical reactions. We will discuss how to determine rate laws from experimental data, and how different reactions orders affect the overall rate. We also discuss integrated rate laws, their importance in reaction analysis and how they can be determined.
Reaction Mechanisms
A reaction mechanism is the process by which reactants are transformed into products. We will examine different types of reactions mechanisms, including elementary reactions, complex reaction, and successive reactions. We also discuss the influence of reaction intermediates on the overall reaction rate.

The study of carbon-based molecules is organic chemistry. This part explores the complexities of organic reactions, the functional groups and the principles that underlie synthetic strategies. We also explore different organic compounds and their everyday applications.
5.1 Functional Groups
Functional groups are atom arrangements that give organic molecules distinct properties and reactivity. We will explore the most common groups and their impact on the behavior of organic compounds. We also discuss the nomenclature principles for various organic functional group.
Reaction Mechanisms of Organic Chemistry
Organic reactions are characterized by the formation and breaking of covalent bonds. They transform one organic compound into another. In this section we will examine key reactions, such as substitution, addition and elimination, and rearrangement. We examine reaction intermediates, reactions arrows, as well as conditions that determine selectivity.
6. Inorganic Chemistry
Inorganic chemistry is the study of compounds that do not contain carbon. We will explore the properties of inorganic compounds, their structures and reactions. We examine various inorganic compounds, elements, and materials to shed light on their synthesis, and their applications in different industries.
6.1 Coordination Chemistry
Coordination chemistry is concerned with the bonding of metal ions, ligands and their behavior. This section examines coordination compounds, their geometries, coordination numbers, and structures. We examine important theories, such as crystal-field theory and ligand-field theory, to better understand the influence of ligands in coordination complexes.
Inorganic Reactions
Inorganic reactions include a wide variety of processes that involve non-carbon compounds. We discuss redox, acid-base, precipitation, and complexation. We examine the driving forces behind these reactions, as well as the factors that determine their feasibility.
7. Analytical Chemistry
Analytical Chemistry focuses on the identification of chemical species, their separation, and their quantification. This part explores the various analytical techniques that are used to determine chemical compositions, concentrations and purity of substances.
