- a b. c. DATA ANALYSIS - (performed individually) Convert all the reaction times for your data in Part B into seconds (S), then determine the rate of each reaction (8-5). (Recall that rates are always something" per unit of time.) Determine the concentration of iodate ion for all reactions in Part B. (Hint: iodate ion has been diluted.) CIVICZV2 Prepare a graph of your data from Part B, as discussed in the introduction. The graph should plot InRate) vs. In([10; 1). Follow all good graphing conventions identified in Appendix C. 4. Using the equation generated by your trendline, determine the order of the reaction with respect to iodate ion ma siope The order of the reaction with respect to bisulfite ion is 2. Use this information along with your own experimental data to write the rate law for the reaction between iodate ion and bisulfite ion Use the rate law to solve for the rate constant (6) for each reaction performed in Part C. (Remember that all reactants have been diluted.) & Prepare a graph of In(k) vs. 1/T, where temperature must be in Kelvins. h. From the slope of your trendline, determine the energy of activation for the reaction between jodate ion and bisulfite ion. (Hint: refer to En 7.6 for guidance.)

Predict what would happen to the rate of reaction if you used solid potassium iodate crystals in Parts B and C instead of a solution of potassium iodate. Explain the reasons behind your prediction 2. Based on your understanding of the conditions that are required for a reaction to occur, explain why temperature affects the rate of reaction. 3. Identify whether each of the following errors are random or systematic. Refer to Appendix D ("Statistics and Error") for assistance. Error Random Systematic Inconsistent addition of the bisulfite ion in Part B. Starting the timer before the bisulfite ion has been added. Removing the cold" reaction from the ice bath before the solution turns dark
