1. Consider the graph at right. It represents the [C] as a function of time in the reaction: A+BC a. On the graph at right draw three lines representing 1) the initial rate 2) the instantaneous rate at 30sec 3) the instantaneous rate at 70sec b. For which of the three lines you drew in part a is the instantaneous rate the fastest? Answer c. At time =0, the concentration of the reactants is A. the highest they will be during the reaction. B. the lowest they will be during the reaction. C. somewhere between the highest and lowest they will be during the reaction. d. How are your answers in part b and c related? 2. a. In the reaction AB, the rate of reaction triples when the concentration of [A] is tripled. What is the correct value of m in rate =k[A]m ? Answer b. What is the value of m if the rate is unchanged when [A] is tripled? Answer 3. The reaction M+NP is found to be third order overall. Write all the possible rate laws rate =[M][N] en assuming that m and n are zero or positive integers: Answe 4. Each of the following rate laws describe a reaction with A+B+CD. Determine the order with respect to A, to B, to C, and the overall order. A B C Overall a. rate =k[A]2[B] b. rate =k[A][B]2 c. rate =k[A][B][[C]k d. rate =k[B]2
