Theory of reaction rates
Webb29 maj 2024 · Collision Theory (i) The basic requirement for a reaction to occur is that the reacting species must collide with one another. This is the basis of collision theory for … WebbIn chemistry, transition state theory ( TST) explains the reaction rates of elementary chemical reactions. The theory assumes a special type of chemical equilibrium (quasi-equilibrium) between reactants and activated transition state complexes. [1] TST is used primarily to understand qualitatively how chemical reactions take place.

WebbIn the theory of absolute reaction rate or the transition-state theory which was developed by Eyring, Glasstone and Laidler, attention is focused on the activated complex. The … Factors that influence the reaction rate are the nature of the reaction, concentration, pressure, reaction order, temperature, solvent, electromagnetic radiation, catalyst, isotopes, surface area, stirring, and diffusion limit. Some reactions are naturally faster than others. The number of reacting species, their physical state (the particles that form solids move much more slowly than those of gases or those in solution), the complexity of the reaction and other factors can greatly i…
