I need help with all of these. Thank you

1. Considering the volumes and concentrations used in Mixture 1, assuming the reaction volume does not change. - What percent of the moles of S2O82 present have been consumed during the timed reaction? - How has the I1 concentration changed (quantitatively) during this same time? 2. The following step by step equations for the slow reaction have been suggested as a possible mechanism: S2O82+I1+H2O2SO42+HIO(aq)+H+HIO(aq)+H++I1I2(aq)+H2O Overall reaction: Add (1) and (2) to give the overr-all slow reaction. Does this seem to be a reasonable mechanism, in accordance with your experimental data? Which of these would be the slow, rate determining step? Explain your answers. 3. Make a sketch below of potential energy versus reaction coordinate, similar to Figure 10-2, but this time for your experimental reaction I1+S2O82I2(aq)+2SO42H=322J Use your values for the activation energies Ea with and without a catalyst, and the above heat of reaction, H.
