###### CHEM125 ILLINOIS INS itute Experiment 3: TECHNOLOG Chemical Kinetics Rate of Reaction Post-lab Questions ( [ Opts)It has been found that in acid solution (grealer than MH ) the reaction of H,Oz with rale expression for the is ofthe form rate k [HzOzI[I ] where k, 0.25 L? mol 25"C. Therefore the rate law over the whole range of acidity from very acid solutions to neutral solution is given by two-term rate expression:rate k[HzOz][T-] + kz[HzOzl[-J[H+]where k, has the value of 0.0115 Lrmol &#x

Compare the relative magnitudes of these = [WO terms under the conditions employed in your rate measurements for mixture in beaker # (You should find that the second term makes negligible contribution to the reaction rate at Ht concentrations smaller than 10 5
