Cell Potential and Free Energy02:58

Cell Potential and Free Energy

46.7K
Thermodynamics of a Redox Reaction
Thermodynamics is the branch of physics dealing with the relationship between heat and other forms of energy. In an electrochemical cell, chemical energy is converted into electrical energy.
Thus, a link can be predicted between cell potential, free energy change, and the equilibrium constant for the reaction. Cell potential can also be measured as the oxidant or the reducing strength, and similar acid-base strength measures are reflected in equilibrium...

Potential Energy

42.9K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

Potential Energy

1.0K
A conservative force, such as a gravitational or elastic force, gives the body the capacity to do work. This capacity, measured as the potential energy, depends on the body's location or “position” relative to a fixed reference position or datum. The gravitational potential energy is considered zero at the reference point. Suppose a body is located at some vertical distance above a fixed horizontal reference or datum. In that case, the weight of the body has positive gravitational potential...

Surface Tension and Surface Energy01:16

Surface Tension and Surface Energy

3.3K
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

Explicit Memories01:27

Explicit Memories

467
Explicit memories, also known as declarative memories, are consciously remembered, recalled, and reported. Studying for a chemistry exam involves material that will become part of explicit memory. There are two types of explicit memory: episodic and semantic.
Episodic memory contains information about personally experienced events and is reported as a story. An example of episodic memory is recalling a birthday celebration. This type of memory includes the what, where, and when of an event, as...

Types of Potential Energy01:16

Types of Potential Energy

10.1K
Potential energy is also known as energy at rest or stored energy. Common types of potential energy include the gravitational potential energy stored in an apple hanging from a tree, the electrical potential energy stored in an object due to the attraction or repulsion of electric charges, and the chemical potential energy stored in the bonds between atoms and molecules. Additionally, the nuclear energy stored in an atomic nucleus and the elastic energy stored in a stretched spring due to its...

Area of Science:

  • Chemical Physics
  • Computational Chemistry
  • Theoretical Chemistry

Background:

  • Accurate potential energy surfaces (PES) are crucial for understanding molecular reaction dynamics.
  • Previous PES for the CNO system had limitations in describing short-range and long-range interactions.

Purpose of the Study:

  • To develop a new global double many-body expansion potential energy surface for the ground state of the CNO(2A') manifold.
  • To provide a more accurate and comprehensive PES for dynamics studies involving CNO and NCO.

Main Methods:

  • Ab initio calculations using the explicit correlation multireference configuration interaction (XMC-QD) method.
  • Fitting 3701 calculated points to a double many-body expansion functional form.
  • Systematic characterization of stationary points and isomerization pathways.

Main Results:

  • A new global double many-body expansion PES for CNO(2A') was generated.
  • The PES was fitted to 3701 ab initio points with a root mean squared deviation of 0.99 kcal mol-1.
  • Improved description of stationary points, including three new ones, and characterization of the CNO to NCO isomerization transition state.

Conclusions:

  • The novel PES accurately describes both short-range and long-range interactions.
  • The developed PES is suitable for future dynamics studies of the CNO system.
  • This work provides a significant advancement in the theoretical understanding of CNO chemistry.
