4. Info: In a reaction between acetone and iodine, 1-iodo acetone molecule is formed. Since one of the reactants is ly, it is possible to follow the progress of the reaction with the method of iodimetry. The reaction between 0.02 M acetone and 0.02 M iodine is initiated in a 1000 ml reaction vessel. In order to determine the half-life of this reaction, 10 mL of sample from the reaction vessel at certain times was taken after the reaction has initiated. Each sample taken was titrated with standard 0.02 M sodium thiosulfate, separately. The consumption of sodium thiosulfate for the samples taken at 15, 25, 35, and 45 minutes were given below: Time 15 min 25 min 35 min 45 min Titrant used 16 mL 13 mL 10 ml 5 mL According to the data given, find the reaction's half-time. (35 p) Hint: Half-life in this case is the point where la reaches half of the its initial concentration.
