 Hey guys, I've been reading my textbook but I still have no clue what rate law is or how to apply it. I must still be in summer mode because it just doesn;t stick to my brain. I really really don't understand.

A + B -> C

so the rate law can be written as:
Rate = k[A]^m{\^n

o >> [A]o

o = 4.1*10^-2 M        y=-9.0*10^-3x + 0.31
o = 4.6*10^-1 M        y=-9.0*10^-3x + 0.71
These values are for a regressional line obtained for 1/A vs t



you with me so far? bcuz i was pretty lost at that point lol.  
anyways so I figure that this is a 2nd order rate law, so the slope of the line = k
so k must equal to -9.0*10^-3

I need to find the value of m and n.
my math math skills were always fairly weak so how would i figure out those values? any hints? please?

oops! typo -  Rate = k[A]^m^n

ok i for sure figured out the k value.

so, because the slope of the line is only linear when it is 1/[A] vs t, this means that it is a 2nd order rate meaning that the k value has to be positive. so i just multiplied the slope by -1.

so now that i have the k value - how do i determine the m and n values?
