Physics of a chemical reaction: looking for textbook recs

Click For Summary

Discussion Overview

The discussion centers on the physics of chemical reactions, particularly in the context of ultracold chemistry, collisional theory, and quantum phenomena. Participants explore the theoretical underpinnings of chemical reactions, including thermodynamics and kinetics, and seek recommendations for textbooks that address these topics from a physical perspective.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant is conducting a literature review on ultracold chemistry and seeks textbooks that discuss chemical reactions from a physics standpoint, particularly focusing on interactions with nuclei and local fields.
  • Another participant mentions the historical context of molecular orbital theory and its relevance to understanding chemical reactions, noting the advancements in quantum theory and computational chemistry.
  • A third participant distinguishes between the thermodynamics of chemical reactions, which involves understanding bond formation and breaking, and the kinetics of reactions, which relates to the speed of reactions and collision theory.
  • This participant also references key concepts such as the Arrhenius equation, Eyring equation, and transition state theory, suggesting that these are relevant to the kinetics of gas-phase reactions.
  • A later reply suggests Linus Pauling's "The Nature of the Chemical Bond" as a potential resource, while also highlighting the complexity of defining "chemical bond" and its dependence on various factors.

Areas of Agreement / Disagreement

Participants express varying perspectives on the best approaches to understanding chemical reactions, with some focusing on thermodynamics and others on kinetics. There is no consensus on specific textbook recommendations, and the discussion remains open-ended regarding the best resources for the proposed topics.

Contextual Notes

Participants note the complexity of quantum mechanics in relation to chemical bonding and the potential limitations of existing textbooks in covering the quantum chemical theory of reactions, particularly concerning field interactions.

I'm currently doing a literature review on ultracold chemistry with an emphasis on collisional theory and quantum phenomena. I'm an undergraduate physics major, and I'd start my discussion of this topic by moving from basic Newtonian conservation laws and concepts like Coulomb repulsion to the idea of chemical reactions occurring. I'm hoping to move downward from statistic models presented in thermodynamics to considering a chemical reaction ( for example a sea of cations and anions forming salt or simple covalent bonding) from the principles of cross-sectional interactions and field interaction, but I need to consult some textbook addressing the physics and chemistry.

Does anyone have any textbooks they are fond of that describe chemical reactions from a physical/physics interpretation, particularly how one describing the interactions through interactions with the nucleus and surrounding local fields involved in the reactions?

Earlier development of theory of chemical reactions lead to Nobel going to Hoffmann and Fukui. The molecular orbital theory of chemical reaction might give you an intuitively easy explanation. If you are going past that, then I don't know. The quantum theory of chemical reactions is a relatively new field of chemistry, and sophisticated calculations only came after development of computational chemistry with the introduction of high-performance computers in the past few decades. I am not sure if we can find a textbook exclusively on quantum chemical theory of reactions, especially when concerning fields. I am also curious to know.

It seems like there might be two different issues here that most chemists would study separately:
1. The thermodynamics of chemical reactions (i.e. which bonds break and which bonds form in a chemical reaction). This would be the topic with the most complicated quantum mechanics to understand the nature of the chemical bond.

2. The kinetics of chemical reactions (i.e. how fast to chemical reactions occur). Here, the connections to collision theory and statistical mechanics are more relevant. This topic involves the kinetic theory of gases, the Arrehnius equation, the Eyring equation, and transition state theory. The quantum mechanics from above would be relevant to finding the energy landscape that defines the transition state and activation energy (though how one performs such calculations is beyond my knowledge).

Not sure of which textbooks might be helpful, but perhaps this helps focus your search. For kinetics, most physical chemistry or chemistry-focused stat mech texts should have chapters on the kinetic theory of gasses and its relation to the kinetics of gas-phase reactions (though perhaps you are already familiar with these concepts).

Linus Pauling, The Nature of the Chemical Bond, excepting the fact that "chemical bond" is a "flexible" term, ranging from inter-atomic attractions/repulsions between He atoms depending upon which side of the the Joule-Thomson inversion temperature one happens to be; i.e., "overlap integrals" have been around a long time.
