Question

3. (1 point) How many moles of peroxide must react before the solution turns blue in Reaction for this Lab In this experiment, the reaction to be studied is 31. (aq) + H2O2 (aq) + 2H. (aq) ½ (aq) + 2H20(1) This is a redox reaction. The hydrogen peroxide oxidizes two I ions to l2, molecular iodine, which then combines with a third r ion in a non-redox reaction to form th lai anion. We will express the rate of this reaction in terms of the formation of product as Rate AUil = 31 At The rate law for this reaction is Ar The exponents x, y, and z must be established experimentally, by changing the concentration of one of the reactants, and then assessing the degree to which the experimental reaction rate changes. To simplify this lab, all the reactions will be run in the presence of a large excess of H'. Because of this excess, the [H'] will not change significantly during the course of any if the reactions. Since the [H']w be constant for all the reactions, we can eliminate [H'] from the rate equation, so eq (9) can be simplified to Rate = 1il (10)

Explanation / Answer

As per reaction stoichiometry 1 mole of H2O2 reacts with 3 moles of I- for reaction completion for blue colour of I3- to appear.
