The reaction of the persulfate ion with the iodine ion at room temperature is: S2O82-...

The reaction of the persulfate ion with the iodine ion at room temperature is:

S₂O₈^2- + 2 I^- ↔ 2 SO₄^2- + I₂ , so rate = k [S₂O₈^2-]^x [I^-]^y

The following data was collected at room temperature:

Experiment	[S₂O₈^2-] (M)	[I^-] (M)	Initial Rate (M/s)
1	0.10	0.15	2.61 x 10^-5
2	0.20	0.15	5.21 x 10^-5
3	0.10	0.30	5.24 x 10^-5

Determine the following:

(a) The rate law (including exponents for S₂O₈^2- and I^-)

(b) The rate constant, k

Boil water in a bowl and cool in a room. The air temperature in the room is increasing linearly according to the function Ta (t) = 22 + 0.015t (t in minutes, T in ° C). Assume that Newton's Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. We take the water temperature after 8 minutes and find that it...

If we want to only use frozen water (ice) and room temperature water (room temperature water of four times the mass of the ice), write out the various forms of heat transfer that will occur between frozen water and room temperature water, when the come into contact. Hint: There will be one term of heat transfer from the room temperature water, and three terms of heat transfer in the ice/cold water.

An uncatalyzed reaction has a rate of 4.4 x 10-7 s–1 at room temperature (25 °C). When an enzyme is added the rate is 3.3 x 104 s–1. If the height of the activation barrier for the uncatalyzed rate is 28 kcal/mol, what is the height of the activation barrier for the catalyzed rate? Report your answer in terms of kcal/mol to the nearest tenths. Also, assume the pre-exponential terms for the uncatalyzed and catalyzed reactions are the same.
