Nonequilibrium chemistry is a branch of chemistry that deals with chemical reactions and processes that occur under conditions far from thermal equilibrium. These reactions are crucial in understanding various natural and industrial processes, including atmospheric chemistry, combustion, and catalysis. The study of nonequilibrium chemistry has led to significant advancements in our understanding of complex chemical systems and has numerous applications in fields such as materials science, environmental science, and energy production.
At the heart of nonequilibrium chemistry lies the concept of nonequilibrium thermodynamics, which describes the behavior of systems that are not in thermal equilibrium. This can include systems with temperature gradients, concentration gradients, or external energy sources. Understanding the principles of nonequilibrium thermodynamics is essential for analyzing and predicting the behavior of complex chemical systems. Key factors such as reaction kinetics, transport phenomena, and energy transfer play crucial roles in determining the outcome of nonequilibrium chemical processes.

Chemical kinetics plays a crucial role in nonequilibrium chemistry, as it describes the rates of chemical reactions and the mechanisms by which they occur.
Principles of Nonequilibrium Thermodynamics
The principles of nonequilibrium thermodynamics are based on the concept of local equilibrium, which assumes that small regions within a system are in thermal equilibrium, even if the system as a whole is not. This concept allows for the application of equilibrium thermodynamic principles to nonequilibrium systems. Key equations, such as the heat equation and the mass transport equation, are used to describe the behavior of nonequilibrium systems. Understanding these principles is essential for analyzing and predicting the behavior of complex chemical systems.
