Table 1 with temperature and rate constants Temperature (oC) Rate constants KH (min-1) 61.0 7.13*10-6 71.2 2.77*10-5 Mark and Anthony have considered the following reaction for urea NH2CONH2 in 0.1M HCl: NH2CONH2 + 2H2O --> 2NH+2 + CO2-3 and the rate constant for the reaction is k1. Stephan and Kurt have been in the laboratory and measured rate constants for the reaction at two different temperatures. The measurement results are given in Table 1. 1) You must write down expressions for the changes in time for the concentrations of the reactants and products. That is, determine d[X]/dt, where [X] is the concentration of either reactants or products and write this down using concentrations and the rate constant. 2) You must use the Arrhenius expression to determine the activation energy for the reaction. 3) You must use the Arrhenius expression to determine the pre-exponential factor in the Arrhenius expression.

The iodide-catalyzed decomposition of hydrogen peroxide is thought to proceed by a four-step mechanism: H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq) (slow)HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq)OI-(aq) + H2O2(aq) --> HOOI(aq) + OH-(aq)HOOI(aq) + OH-(aq) --> H2O(l) + O2(g) + I-(aq) (a) If the first step of this mechanism is rate-determining (slow), choose the correct rate law for the overall process. Rate = k [HOI] [H2O2] Rate = k [H2O2]2 Rate = k [I-] [H2O2] Rate = k [H2O2]2 [H2O2] Rate = k [I-] [HOI] Rate = k [H2O2] [H2O2] (b) Choose the correct chemical equation for the overall process. HOI(aq) + OH-(aq) --> H2O(l) + OI-(aq) H2O2(aq) + I-(aq) --> HOI(aq) + OH-(aq) 2 H2O2(aq) --> 2 H2O(l) + O2(g) (c) Identify an intermediate in the reaction.
