Order of Reaction?
Plz,share with me ur valueable knowledge in understanding this problem that is tricking in mind every second.
Answer:
well, reaction kinetics in not as simple as it seems on paper. although we can write a penta-molecular reaction, statistics say, that more than tri-molecular reactions just do not happen.
in reality, reactions are usually multistep, the laws describing the kinetics are generally applicable only for the rate-determining step, which is not always easy to identify. (and there might be two of those, with very close K´s, further complicating life) a further complication comes from the use of catalyst, and especially enzymes.
bottom line, fractal orders are usually experimental results, and there are usually explained by dependent slow reaction steps.
If you have a complicate reaction, that takes place in 2 or more than 2 steps, from experimental data you obtain a very complicate expression for the reaction velocity, and you also obtain fractional numbers for the order of the rxn
well, for example, the conc'n you got is 1, and the rate of rxn is halved. when the conc'n of the cpd is halved, the rate of rxn is 1/4... if this is the case, you have a fractional order of the rxn.
