Convex Arrhenius plots and their interpretation.
This paper draws attention to selected experiments on enzyme-catalyzed reactions that show convex Arrhenius plots, which are very rare, and points out that Tolman's interpretation of the activation energy places a fundamental model-independent constraint on any detailed explanation of these reactions. The analysis presented here shows that in such systems, the rate coefficient as a function of ...
متن کاملCorrelations in Nuclear Arrhenius-Type Plots
Arrhenius-type plots for multifragmentation process, defined as the transverse energy dependence of the single-fragment emission-probability, (ln(1/pb) vs 1/ √ Et), have been studied by examining the relationship of the parameters pb and Et to the intermediate-mass fragment multiplicity 〈n〉. The linearity of these plots reflects the correlation of the fragment multiplicity with the transverse e...
متن کاملErrors in the evaluation of Arrhenius and van't Hoff plots.
Errors in the numerical values of activation or normal enthalpies, entropies and free enthalpies calculated from Arrhenius or van't Hoff plots, respectively, are due to the neglect of equidimensionality in equations, or to inappropriate approximations. The logarithmization of dimensioned quantities should be avoided, which demands the use of relative concentrations if a change in mole number oc...
متن کاملA caveat for single-molecule magnetism: non-linear Arrhenius plots.
Single-molecule magnets (SMMs) are molecules that, below a certain temperature (TB), function as individual nanoscale magnetic particles, exhibiting magnetization hysteresis loops. As such, they represent an alternative and molecular (bottom-up) route to nanomagnetism, complementing the top-down approach to traditional magnetic nanomaterials. SMMs also exhibit fascinating quantum behavior such ...
متن کامل1 1 Box plots : use and interpretation
Abox-and-whisker plot, often referred to as a box plot, was developed by John Tukey.1 It is a convenient graphic tool in descriptive analysis to display a group or groups of numerical data through their medians, means, quartiles, and minimum and maximum observations. A box plot is useful to display the distribution of data, examine symmetry, and indicate potential outliers and can also be used ...
