Kinetics of the reaction between iodide and persulfate

Reference no: EM13634788

Kinetics of the Reaction Between Iodide and Persulfate. Procedure: popet 4 mL of the idoide solution and 12 mL ofdistilled water into a small beaker labeled A. now pipet 4 mL ofthe persulfate solution provided into the other beaker labeled B.Quickly mix the solutions by pouring the solutions back and forthfrom beaker A to beaker B and back again several times. Fill acuvette with the solution ( yellow color) begin to measure theabsorbance at 540nm every 10 seconds for at least two minutes.Measure roo temerature and record it Assume that room temperatureis the same as the temperature of the reaction.

Rate law for this reaction would be given by
Rate =k[I-1]x[S2O8-2]y
Pre-lab questions
1. Write the general rate law for the reaction studied inthis experiment
2I-1 + S2O8-22SO4-2+ I2

2. Which variable in the general rate lawrepresents:
a) the order of the reaction with respect toidoide ion:
b) the order of the reaction with respect topersulfate ion:
c) the rate constat:

3. How will the concentrationof iodine be determined in this experiment? please give me good explanation.
