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.

What is the first-order reaction formula used to determine the rate of a chemical reaction?
The first-order reaction formula used to determine the rate of a chemical reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
What does the rate law use to determine the rate of a reaction?
The rate law uses the concentrations of reactants to determine the rate of a reaction. By experimentally determining the relationship between the rate of reaction and the concentrations of reactants, we can derive the rate law equation for that specific reaction.

What is necessary to determine the rate of a reaction using the rate law?
To determine the rate of a reaction using the rate law, you need to know the rate constant (k), the concentrations of the reactants, and the order of the reaction with respect to each reactant. The rate law equation relates the rate of the reaction to these factors.
What does the law use to determine the rate of a reaction?
The rate of a reaction is calculated using the concentrations of reactants.
What of the following is necessary to determine the rateof the reaction using the rate law?
To determine the rate of the reaction using the rate law, you need the rate equation that relates the rate to the concentrations of reactants. It is also essential to have experimental data, such as the initial rates of reaction at different concentrations of reactants, to determine the rate constant and the order of the reaction with respect to each reactant.
How can one determine the rate law of a reaction?
To determine the rate law of a reaction, one can conduct experiments where the concentrations of reactants are varied and the initial rates of the reaction are measured. By analyzing how changes in reactant concentrations affect the rate of the reaction, one can determine the order of the reaction with respect to each reactant and ultimately write the rate law equation.
What are the methods for the determination of rate of reaction?
In this method we determine the rate of reaction physically.in this method we put the sample in machine and thus we determine the reaction rate.it is very easy method.
