Determining Order

$aR \to bP, Rate = -\frac{1}{a} \frac{d[R]}{dt} = \frac{1}{b}\frac{d[P]}{dt}$

Determining Order

How do you determine order of a reaction?

Re: Determining Order

let's say: rate = [A]^m * [B]^n

the order of reaction = m + n

I hope this helps!

^^ like they said, and how you determine the m and n is the coefficients of the reactants in the overall reaction

Re: Determining Order

Can the order keep increasing? Or do they stop at two?

Order can be higher than two, but they become less common the higher order you go. It is harder for three molecules to collide than for two molecules to collide. The same goes for higher orders.
