Example of Frost diagram for the manganese species. A Frost diagram or Frost–Ebsworth diagram is a type of graph used by inorganic chemists in electrochemistry to illustrate the relative stability of a number of different oxidation states of a particular substance.
Frost diagram for manganese In electrochemistry , the tendency of two redox species to disproportionate, or comproportionate, can be determined by examining their Frost diagram . It is a graphical plot of nE ° = −Δ G °/ F as a function of the oxidation number for the different redox species of a given element.
This article is confused and confusing. There are a number of commonly used diagrams, the Latimer diagram, the Frost (sometimes called Frost - Ebsworth) diagram and the pourbaix diagram (also known as Eh-pH diagrams). They are all closely related. A good summary is here . The article seems to describe both the Frost and pourbaix as being the ...
Latimer diagrams can be used in the construction of Frost diagrams, as a concise summary of the standard electrode potentials relative to the element. Since Δ r G o = -n F E o , the electrode potential is a representation of the Gibbs energy change for the given reduction.
A circle mnemonic [3] was advanced which provides the MO energies of the system; this was the counterpart of the Frost–Musulin mnemonic [6] for ordinary Hückel systems. It was concluded that 4 n electrons is the preferred number for Möbius moieties in contrast to the common 4 n + 2 electrons for Hückel systems.
The energy levels for cyclic systems can be predicted using the Frost circle mnemonic (named after the American chemist Arthur Atwater Frost ). A circle centered at α with radius 2β is inscribed with a regular N- gon with one vertex pointing down; the y -coordinate of the vertices of the polygon then represent the orbital energies of the [ N ...
A three-component compatibility diagram will depict the stable phase of each pure component as the point at each corner of a ternary diagram. Additional points in the diagram represent other pure phases, and lines connecting pairs of these points represent compositions at which the two phases are the only phases present.
For the full specification of the model, the arrows should be labeled with the transition rates between compartments. Between S and I, the transition rate is assumed to be (/) / = /, where is the total population, is the average number of contacts per person per time, multiplied by the probability of disease transmission in a contact between a susceptible and an infectious subject, and / is ...
