unimolekylär
Unimolekylär refers to a process or reaction that involves a single molecule. In chemistry, a unimolecular reaction is a reaction in which, on the molecular scale, only a single molecule is involved in the rate-determining step. This means that the reaction rate depends only on the concentration of that single reactant molecule. For example, the decomposition of a molecule into two or more fragments is a common type of unimolecular reaction. Another example is the rearrangement of atoms within a single molecule to form an isomer.
The concept of unimolecularity is fundamental in chemical kinetics, the study of reaction rates. While reactions
In biological contexts, unimolecular processes can also occur. For instance, the conformational change of a protein
