Reaction Order [ENDORSED]

[Ardo 2K]

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

[Nora Sharp 1C]

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.

[Michelle Nguyen 2L]

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

[Michael Lee 2I]

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

[Ilan Shavolian 1K]

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

[Timothy Kim 1B]

Reaction order would be the exponent for the concentration in the rate law.

[Michelle Lu 1F]

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.
