Question
The rate of appearance of I2 in aqueous solution, in the reaction of the I- ion with hydrogen peroxide, was found to change from 3.7*10^-5 mol/dm^3 to 7.9*10^-5 mol/dm^3 over a time interval of 1.0 to 3.0s.
2H+(aq) + 2I-(aq) + H2O2(aq) --> I2(aq) + 2H2O(l)
a)What is the rate of appearance of H2 during this period?
b) At what rate should the concentration of the H+ ion be changing during this same time period?
c) Is this mechanism likely to occur in one step?
Attempt
a) rate(H2) = rate(I2)
rate(H2)=delta/delta t
