I am having trouble coming up with the slow and fast reaction for the iodine clock lab that I did. I also don't know how to figure out the rate law. Here are the things I used..
Solution 1
1.0 grams Starch
10.0 mL of Acetic Acid
4.1 grams of Sodium Acetate
Sodium Iodide 1, 2, 3 g
1.57 grams of Sodium Thiosulfate
Solution 2
500 mL of 3% Hydrogen Peroxide
500 mL of distilled water
I mixed the two solutions together in the course of three trials and increased the concentration of sodium iodide. With reference to rate=k [A]m [ B]n, what is A and B? What is the slow and fast reaction. I used sodium iodide and i don't know where to go from here in terms of rate law.
