a) I found this data when comparing 5 different reactions, using various concentrations

When S2O8] remains constant (0.0400M):

Reaction 1 and 2: The [I-] concentration doubles from 0.0400M to 0.0800M, while the rate and relative rate triple at 4.31e-6M/s to 1.32e-5M/s and 2.00 to 6.14

Reaction 2 and 3: The [I-] concentration quadruples from 0.0200M to 0.0800M, while the rate and relative rate multiply by 6 from 2.15e-6M/s to 1.32e-5M/s and 1.0 to 6.14

Does this prove that the [I-] concentration is proportional to the rate in a fashion of 3/2, 2/3 or another ratio?

b) Using this data, In the rate law
rate=k[I-]n[S2O82-]m
what is the value of n?

Osmosis occurs when two solutions of different concentrations are separated by a semipermeable membrane. The membrane allows solvent particles, but not solute particles, to pass through. Thus, the solvent moves toward the solution of higher concentration (to dilute it) until the two solutions have the same concentration, or until gravity overtakes the osmotic pressure, Π. The osmotic pressure between a solution and pure solvent depends on the number of solute particles and thus is a colligative property. It can be...
