le (chl528) – Homework 10 – Sutcliffe – (52440) 1 This print-out should have 20 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. This is the LAST homework!! 10.0 points NOTE: In this question the equation is assum- ing you INCLUDE the 1/a term for species A. Consider the reaction What is another form of the rate of thereaction? 4. Δ[NO 2 F] 2 Δ t correct 5. Δ[NO 2 F] Δ t Explanation: 002 10.0 points Consider the concentration-time dependence graph for two first-order reactions. [A] 0 Molar Concentration of Reactant Concentration -→ Which reaction has the larger rate con- stant? 3.Unable to determine For BOTH the next questions you MUSTconsider the 1/a term in the rate equationfor species A, etc.A ”unique rate” means’average rate’ taking into account the stoi-chiometric coefficients.In the reaction What is the rate of reaction of ClO? 1. 0 . 9 mol L · min 2. 10 . 8 mol L · min 3. 5 . 4 mol L · min correct 4. 1 . 8 mol L · min 5. 2 . 7 mol L · min Explanation: rate of change of [ClO ] = parenleftbigg 3 . 6 mol Cl L · min parenrightbiggparenleftbigg 3 mol ClO 2 mol Cl parenrightbigg = 5 . 4 mol L · min 004 (part 2 of 2) 10.0 points What is the unique rate of the reaction?
