Reaction Order
So do the reaction orders of reactions depend upon the amount of moles decomposed in a standard decomposition reaction?

Re: Reaction Order
I believe the reaction order does depend on the number of coefficients involved the reaction, but it more specifically depends on the coefficients of the reactants involved in the slow step.

Re: Reaction Order
I'm not sure if the two are related in some convoluted way, but as of right now at least, we cannot determine the order of a reaction simply by looking at the chemical formula and stoichiometric coefficients of the reaction. For example A->B might be a first order reaction, but so might 3A->2B+C

Re: Reaction Order
I think it's more of just the exponent of the [A]. For example k[A]^2 would be a second order reaction

Re: Reaction Order [ENDORSED]
there is a difference between a chemical reaction and a reaction mechanism. a reaction mechanism tells us exactly what is happening, so we can say the order. but with a simple chemical reaction we don't know what exactly is happening so we can't say the order

Re: Reaction Order
Reaction orders, along with the rate constant (k), can only be obtained experimentally. This would mean plotting points with respect to each reactant in graphs comparing [A], ln[A], and 1/[A] to time, and observing which graph is the most linear for that respective reactant. Then, to find the overall reaction order, you would add the individual orders of each reactant.
