The Basics of Thermodynamics

Before we embark on our journey into the complexities of thermodynamics kinetics and reaction path modeling, it is essential to grasp the fundamentals. Thermodynamics is the branch of science that deals with energy and the relationships between different forms of energy. It allows us to quantify and predict how energy flows and transforms in a system.

Thermodynamics can be divided into two main laws:

First Law of Thermodynamics

The first law, also known as the law of conservation of energy, states that energy cannot be created or destroyed but can only change form. This law forms the foundation for understanding the transfer of energy in various processes, including chemical reactions.

Second Law of Thermodynamics

The second law of thermodynamics introduces the concept of entropy, which is a measure of the disorder or randomness in a system. It states that in any spontaneous process, the total entropy of an isolated system always increases. This law helps us understand why certain reactions occur spontaneously while others require external energy input.

Kinetics: Understanding Reaction Rates

Now that we have a basic understanding of thermodynamics, let's dive into kinetics, which focuses on the rate of chemical reactions. Kinetics allows us to shed light on how quickly or slowly a reaction proceeds and the factors influencing its rate.

Multiple factors affect the rate of a reaction, including:

Concentration of Reactants

The concentration of reactants directly affects the chance of successful collisions between molecules, leading to a reaction. Higher concentrations generally result in faster reaction rates.

Temperature

Temperature plays a crucial role in reaction rates. As the temperature increases, particle kinetic energy increases, resulting in more frequent successful collisions and faster reactions. The relationship between temperature and reaction rate is described mathematically by the Arrhenius equation.

Catalysts

Catalysts are substances that speed up chemical reactions without being consumed in the process. They provide an alternative reaction pathway with a lower activation energy, making it easier for reactant molecules to overcome the energy barrier and react.

Reaction Path Modeling: Predicting the Future

Once we have a comprehensive understanding of thermodynamics and kinetics, we can utilize reaction path modeling to predict the future behavior of chemical reactions. Reaction path modeling involves using computational methods to simulate and analyze chemical reactions.

By applying concepts from quantum mechanics and statistical mechanics, scientists can build models that accurately represent the potential energy surfaces of reactants, intermediates, and products. These models provide insights into reaction mechanisms, transition states, and reaction pathways.

The advent of powerful computers and sophisticated software has revolutionized reaction path modeling. Researchers can now perform complex calculations and simulations to predict reaction outcomes, optimize reaction conditions, design catalysts, and even discover entirely new reactions.

The contents of this monograph are two-scope. First, it intends to provide a synthetic but complete account of the thermodynamic and kinetic foundations on which the reaction path modeling of geological CO2 sequestration is based. In particular, a great effort is devoted to review the thermodynamic properties of CO2 and of the CO2-H2O system and the interactions in the aqueous solution, the thermodynamic stability of solid product phases (by means of several stability plots and activity plots),the volumes of carbonation reactions, and especially the kinetics of dissolution/precipitation reactions of silicates, oxides, hydroxides, and carbonates.

Second, it intends to show the reader how reaction path modeling of geological CO2 sequestration is carried out. To this purpose the well-known high-quality EQ3/6 software package is used. Setting up of computer simulations and obtained results are described in detail and used EQ3/6 input files are given to guide the reader step-by-step from the beginning to the end of these exercises.

Finally, some examples of reaction-path- and reaction-transport-modeling taken from the available literature are presented. The results of these simulations are of fundamental importance to evaluate the amounts of potentially sequestered CO2, and their evolution with time, as well as the time changes of all the other relevant geochemical parameters (e.g., amounts of solid reactants and products, composition of the aqueous phase, pH, redox potential, effects on aquifer porosity). In other words, in this way we are able to predict what occurs when CO2 is injected into a deep aquifer.
