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 = -nFE o, the electrode potential is a representation of the Gibbs energy change for the given reduction.
Möbius–Hückel correlation diagram; two modes of butadiene to cyclobutene conversion. It has been noted that for every degeneracy along a reaction coordinate there is a molecular orbital crossing. [4] Thus for the butadiene to cyclobutene conversion, the two Möbius (here conrotatory) and Hückel (here disrotatory) modes are shown in Figure 5.
An animated cobweb diagram of the logistic map = (), showing chaotic behaviour for most values of >. A cobweb plot , known also as Lémeray Diagram or Verhulst diagram is a visual tool used in the dynamical systems field of mathematics to investigate the qualitative behaviour of one-dimensional iterated functions , such as the logistic map .
The pressure on a pressure-temperature diagram (such as the water phase diagram shown above) is the partial pressure of the substance in question. A phase diagram in physical chemistry , engineering , mineralogy , and materials science is a type of chart used to show conditions (pressure, temperature, etc.) at which thermodynamically distinct ...
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.
