The orders of reactants and/or products in the rate law may be the same as the stoichiometric coefficients but this is not a requirement. b. TRUE. c. FALSE. In this method, we measure the rate shortly after the reaction begins. This avoids the problems associated with the reverse reaction in equilibrium situations. Therefore, this method can be used for equilibrium. d. FALSE. Transition states cannot be trapped or isolated because they are maxima on the potential energy surface. However, intermediates can sometimes be trapped or isolated because they do have finite lifetimes. 29. - d[ClO 2 ] - d[OH - ] d[ClO 3 - ] d[ClO 2 ] d[H 2 O] 30. ------- = ------- = ------- = ------- = ------- 31. 2 dt 2 dt dt dt dt
