A student studied the clock reaction described in this experiment. She set up Reaction Mixture 2 by mixing 20 mL 0.010 M KI, 10 mL .001 M Na2S2O3, 10 mL .040 M KBrO3, and 10 mL 0.10 M HCl using the procedure given. It took 45 seconds for the color to turn to blue. a. She found the concentration of each reactant in the reacting mixture by realizing that the number of moles of each reactant did not change when...
I just wanted to check if my answers were correct for
the initial concentrations of mixture 4 #7-9.

Iodination of Acetone
1- a student made up a reaction mixture
consisting of 10 mL 4 M acetone, 5 mL 1.0 M HCl 10 mL 0.005 M
I2 and 25 mL H2O.
Why is the concentration of iodine so much lower than the other
reactants?
3. How are time and rate related? How are 1/time and
rate related?
4. What does it mean when someone says a reaction is “first
