an equation that relates the reaction rate to the concentration of the reactants.
Reaction Rates follow the formula:
T=K[a]A[b]B[c]C[d]D............
where
T is the timed period under investigation.
K is a constant
a,b,c,d.... are the reactants and products
[] denotes the concentration of a reactant or a product
A,B,C,D are the unknown exponential components that will determine the order of the reaction.
T is determined by some observable change in the reaction medium. For example in the Iodine clock reaction it is where the solution turns purple.
K is determined by starting all concentrations at 1. Since 1 to any power is still one T=K
To determine the value of A,B,C,D run two timed experiments. The first with all concentrations at one. The second with one and only one of the other components at a concentration of two.
Divide the second run by the first. T2/T1 will give you a ratio.
K will cancel out.
All concentrations of one will still give one and are therefore of no impact.
What you are left with then is:
Ratio =[2]x
If the Ration is 1 then x=0
" " " " " " " 2 then x=1
" " " " " " " 4 then x=2
" " " " " " " 8 then x=3
You will have to make a run altering just one of each component each time to get all exponents.
You will find that products give negative exponents.
The rate constant is the reaction divided by the concentration
by the slope of the graph
