In practice, a reaction is assumed to be elementary if no reaction intermediates have been detected or need to be postulated to describe the reaction on a molecular scale. [1] An apparently elementary reaction may be in fact a stepwise reaction, i.e. a complicated sequence of chemical reactions, with reaction intermediates of variable lifetimes.
A termolecular [4] [5] (or trimolecular) [6] reaction in solutions or gas mixtures involves three reactants simultaneously colliding, with appropriate orientation and sufficient energy. [4] However the term trimolecular is also used to refer to three body association reactions of the type:
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
Now I read the actual definition carefully as well by the strictist application this reaction is not a termolecular reaction but 2 bimolecular ones with the first reaction being reversible. This may be one where the common use of the term "termolecular" in gas kinetics is not strictly speaking the same as its definition here.
In chemistry, the rate equation (also known as the rate law or empirical differential rate equation) is an empirical differential mathematical expression for the reaction rate of a given reaction in terms of concentrations of chemical species and constant parameters (normally rate coefficients and partial orders of reaction) only.

The process theory of composition (hereafter referred to as "process") is a field of composition studies that focuses on writing as a process rather than a product. Based on Janet Emig's breakdown of the writing process, [1] the process is centered on the idea that students determine the content of the course by exploring the craft of writing using their own interests, language, techniques ...

Personal free writing is the practice of writing what one is thinking without considering organization or grammatical errors. In a study done by Fred McKinney, free writing was defined as letting one’s thoughts and words flow onto paper without hesitation. [21] This can be done in the format of letters or even a personal notebook.
