In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 1119-97-7, name is MitMAB, introducing its new discovery. Safety of MitMAB
In this Letter, we show that the shape of a freezing drop of water can be sensitive to the presence of impurities. We measure the tip angle of water drops frozen on a cold plate. The fine changes in the tip angle are robustly captured by our image analysis method, which shows a deviation from that of pure water in solutions with salt (NaCl), polymer polyethylene glycol, and surfactant tetradecyltrimethylammonium bromide starting at concentrations of 10 – 6, 10 – 4, and 10 – 6 M, respectively. The method could be adapted into a portable water purity tester, but this work also highlights the complexity of water freezing as it is influenced by trace concentrations of impurities.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1119-97-7 is helpful to your research. Safety of MitMAB
