Appendix 1: Mechanism of the Mandelate/Permanganate Reaction The first two steps of a possible mechanism for this reaction are shown below. If these reactions correspond to elementary reaction steps, is this mechanism consistent with your finding of the order with respect to permanganate? H OH OH + MnO4 Fast Slow H O H₂O HMnO4

d) The integrated rate law for a reaction, describes how the reaction rate depends on the concentration of reactants. True False

3. Which of the following is NOT TRUE about a catalyst? A) It lowers the activation energy of the reaction. B) It decreases AH for the reaction. C) It changes the mechanism. D) It increases the number of effective collisions. E) It is not consumed in the reaction.

The rate of a reaction is found to double when the concentration of one reactant is quadrupled. The order of the reaction with respect to this reactant is Oa) one-quarter. Ob) one-half. Od second. O di first. Oel third.

Write a balanced reaction for which the following rate relationships are true. Rate (A[NO]/At) = - (1/2)(A[HNO3]/At) = (A[H₂O]/At) = (1/3)(A[NO₂]/At) No +해 + + HNO3 H₂O 1 NO₂ 6 NO3HNO3 6H 20 + 2NO₂ If the rate of disappearance of NO in the reaction in #1 is 0.270 M s-1 at 150°C, the rate of appearance of NO3 is. What is the overall order of the reaction in #1, if given is the rate law? Rate = k[NO]2 [HNO3]³ Ms-1 Given the above rate law, how does the rate of reaction change if the concentration HNO3 is doubled? ANSWER:

For a reaction, if the rate-determining step has a large activation energy, then the rate of the reaction will be very fast. O True O False

A student follows the Determining the Rate Law for the Crystal Violet-Hydroxide lon Reaction procedure. The stock concentration of sodium hydroxide used in trial 1 is 0.021 M. The stock concentration of sodium hydroxide used in trial 2 is 0.010 M. Given the data below, what is the hydroxide ion concentration (M) in the trial 1 reaction mixture? Give your answer to four decimal places. Volume NaOH Volume Crystal Violet (mL) (mL) Trial 1 5.00 5.00 Trial 2 5.00 5.00

The rate of a certain reaction is given by the following rate law: rate =k Use this information to answer the questions below. What is the reaction order in N,? What is the reaction order in H2? What is overall reaction order? At a certain concentration of N2 and H2, the initial rate of reaction is 0.820 M / s. What would the initial rate of the reaction be if the concentration of N2 were halved? Round M S your answer to 3 significant digits. The rațe of the reaction is measured to be 47.0 M/s when [N2] = 1.4 M and [H2] = 0.35 M. Calculate the value of the k = M rate constant. Round your answer to 2 significant digits.

The half-life of a chemical reaction is   the time it takes for half the present reactants to be used up   when a reaction has reached the half-way point   when only half of the reactant is used   the time passed when a reaction is half over
