Table of Contents in Chemical Kinetics and Process Dynamics in Aquatic Systems By Patrick L. Brezonik

Chapter 1: General Overview

The first chapter lays the groundwork for the comprehensive exploration of chemical kinetics in aquatic environments. It starts with an introductory section that outlines the importance of studying reaction kinetics in natural waters. A major theme introduced early on is the nonequilibrium nature of aquatic systems. Unlike idealized closed systems, natural waters are influenced by a wide variety of dynamic factors—biological, chemical, and physical—that keep them in a constant state of flux. This chapter emphasizes how these complexities must be accounted for in any meaningful analysis of environmental chemical behavior. The final part of the chapter defines the broad scope of the book, which includes theoretical foundations, mathematical modeling, experimental approaches, and practical environmental applications.

Chapter 2: Chemical Reaction Rates and Their Expressions

Chapter 2 delves into the fundamental topic of how to describe the rates at which chemical reactions proceed. It begins with an introduction to kinetic concepts and then presents the foundational rate laws for simple, elementary reactions. The discussion then evolves into more complex systems, with equations tailored for reactions involving multiple steps or intermediates. A critical section follows, explaining how scientists determine rate laws and kinetic parameters using experimental data—bridging theory and practice. The chapter also explores how these experimentally derived equations relate to proposed reaction mechanisms, offering insight into the step-by-step pathways of chemical change. Lastly, it covers the experimental techniques and design considerations necessary for accurate kinetic measurements in aquatic systems.

Chapter 3: Theoretical Principles and Physical Influences on Reaction Rates

This chapter explores the theoretical frameworks that underpin reaction kinetics and how physical variables modify reaction rates. It opens with a discussion of the Arrhenius equation and its role in understanding how temperature impacts reaction velocity. The properties of water and dissolved substances are then considered in detail, shedding light on solute-solvent interactions. Encounter theory and transition-state theory are introduced as models that describe how molecular collisions lead to chemical transformations. The effects of pressure and ionic strength on reaction rates are also addressed, highlighting their relevance in natural aquatic settings. The chapter concludes with a comparative summary of typical kinetic parameter ranges, placing theoretical concepts into an environmental context.

Chapter 4: Aquatic Reaction Kinetics from Homogeneous to Interface Processes

Chapter 4 addresses the diversity of chemical reactions in natural waters by organizing the content into three parts. Part I focuses on homogeneous catalysis, including the types of catalysts, their mechanistic roles, and how they affect reaction kinetics. Part II centers on reactions occurring entirely in aqueous solutions, such as dissociation, hydrolysis, chlorination, and inorganic redox reactions. These are common in environmental systems like rivers, lakes, and groundwater. Part III shifts attention to processes occurring at phase boundaries—such as gas exchange at the air-water interface and mineral precipitation or dissolution at solid-liquid interfaces. This chapter highlights the spatial and chemical complexity of natural aquatic systems and the need for multiple kinetic approaches.

Chapter 5: Reactor Models, Mass Transport, and System-Level Processes

Chapter 5 introduces readers to chemical reactor theory as a tool for modeling environmental processes. Part I covers the principles of reactors and mass balances, comparing the behaviors of different reactor types such as CFSTRs and PFRs. These models are essential for interpreting how reactions proceed in open, flowing systems. Part II applies these principles to natural environments, discussing kinetic versus equilibrium modeling, and presenting detailed models for nutrient cycling, organic contaminant fate, and sulfate/alkalinity balances in lakes. Part III introduces multicompartment systems—complex networks where mass and reactions occur in distinct but interconnected zones. Mathematical tools, such as matrix analysis and the inverse problem, are presented to help analyze and interpret these more intricate systems.

Chapter 6: Biochemical and Microbial Kinetics in Aquatic Environments

This chapter explores biological aspects of environmental kinetics, divided into two main parts. Part I focuses on enzyme-catalyzed reactions. It covers single- and multi-substrate kinetics, mechanisms of inhibition, and theoretical models explaining how enzymes enhance reaction rates. Part II turns to microbial processes, beginning with the kinetics of nutrient-limited microbial growth and moving into continuous culture systems. The effects of environmental conditions—especially temperature—on microbial activity are also discussed. Models are presented for heterotrophic and autotrophic microorganisms, addressing how they interact with their chemical environment. The section concludes with discussions on diffusion-limited transport, microbial die-off, and the kinetics of disinfection—all crucial for water treatment and public health.

Chapter 7: Predicting Reaction Rates and Reactivity of Compounds

Prediction methods are the focus of Chapter 7, which is divided into two parts. Part I presents linear free-energy relationships (LFERs), including the Brønsted and sigma relationships, which correlate molecular structure with reactivity. These tools are applied to organic and redox reactions in natural systems. Part II extends the discussion into property-activity and structure-activity relationships (PARs and SARs), which link physical properties or molecular structures to environmental behavior. The chapter explains how solubility, transport, and bioavailability can be predicted using models like UNIFAC and LSERs. Statistical methods for constructing and analyzing PAR and SAR models are also covered, offering a practical pathway to environmental prediction and assessment.

Chapter 8: Photochemical Reactions in Surface Waters

The final chapter addresses the significant role of sunlight in driving chemical transformations in aquatic environments. It opens with a general introduction to photochemistry and then discusses the kinetics of photochemical reactions. The chapter details inorganic photochemistry and the interactions of sunlight with naturally occurring dissolved organic matter (DOM), which can produce reactive species or break down pollutants. Photolysis of organic contaminants is discussed in-depth, emphasizing its importance in surface water cleansing. The final section explores photochemical processes occurring on the surfaces of suspended oxide particles, adding another layer of complexity to how light influences environmental chemistry.
