Spring 2023 Worksheet? Chem 126 Part 2. 1. Integrated rate laws: Consider the decomposition reaction of Hl at 150C. This is a zero-order reaction. At the beginning of the reaction, the fHI]=0.250M. Given k=1.2104M/s, calculate the concentration of [i] remaining after 2.5min 2HH2(g)+H(g). 2. Reaction Mechanisms: One proposed mechanism for the decomposition of N2O5 to NO2 involves the following three elementary steps: Step 12N2O8(g)N4Ojo(g) Fast and reversible Step 2N4O4(g)N2O3(g)+2NO2(g)+O1(g) Slow Step 3N2O3(g)+O3(g)2NO2(g)+O2(g) fast Overall 2N2O(g)4NO2(g)+O2(g) What is the rate law for the overall reaction based on the proposed mechanism? The experimentally determined Rate law =k[N2O5], is the mechanism correct? 3. Catalysts and intermediates: Determine if each molecule/atom in the mechanism below is a catalyst, intermediate, starting material, or product. Step 1O2(s)+NO(s)O2(g)+NO2(s) Step 2NO2(B)NO(B)+O(B) Step 3 O(g) +O1(g)2O2(g) Overall 20,(g)30.(g) 4. Challenge Problem: The reaction below is a first order reaction. The half-life of the reaction is 14.1h at 25C and 48.8 min at 50C. How long will it take, in minutes, for this conversion to go to 908 completion at 65C ? (CH2)3CBr+H2O(CH2)2COH+HBr
