CEM 834 PROBLEM SET 2 FALL 2005 Due at the beginning of class on Friday, September 30, 2005 Please be sure to show all work on every problem to receive credit. If a spreadsheet program such as Microsoft Excel is used in problem solving, please include a copy of the spreadsheet including formulas used. 1. a. Derive the integrated rate law for the general second-order reaction when A + B → C i. [A] 0 = [B] 0 ii. [A] 0 ≠ [B] 0 b. What mathematical expression of the reactant concentrations, when graphed as a function of time, will yield a linear relationship? 2. For the overall reaction V 2+ + VO 2+ + 2 H + ↔ 2 V 3+ + H 2 O a. Determine the rate law for each of the following mechanisms: Mechanism I V 2+ + VO 2+ ↔ V 2 O 4+ Fast (K 1 ) V 2 O 4+ → VO + + V 3+ Slow (k 2 ) VO + + 2 H + ↔ V 3+ + H 2 O Fast (K 3 ) Mechanism II V 2+ + VO 2+ ↔ V 2 O 4+ Fast (K 4 ) V 2 O 4+ + H + → VOH 2+ + V 3+ Slow (k 5 ) VOH 2+ + H + ↔ V 3+ + H 2 O Fast (K 6 ) b.
