reaction order
I know the form is r=k(A)a(B)b (a, b are exponents)
and I know a and b depend on the concentration, but how do i know the number a and b.
can you please explain in your own words instead of giving me websites because i look and i'm still confused
I also tried to post an example, but it wouldn't let me submit my question because it is reading it as a website.

I know the form is r=k(A)^a(B)^b
and I know a and b depend on the concentration, but how do i know the number
For example, 2NO3+2H2>N2+2H2O
r=k[NO3]^2[H2]^1 and 2+1=3 making it a third order equations.

I wish I knew what your question was. Explain what?

the reaction order respect to one reactant.
r is for rate=k(A)^a(B)^b
if you look online, it will tell you but i'm not sure i understand it.
For example, 2NO3+2H2>N2+2H2O
the above reaction is a third order question because a=2 and b=1 which is three. a and b are not the numbers before the formulas.

The reaction orders are determined experimentally. They may or may not be the same as the coefficients in the balanced equation. In the nitrate reaction you cite, the one to the second order has an exponent of 2, the other one is a first order, together they are 2+1 = third order overall.
