Consider the reaction and its rate law given below for the next four questions. 2 A(g) + B(g) → C(g)rate = k[A]2[B] At the beginning of one trial of this reaction[A] = 4.0 M and [B] = 1.0 M The rate of formation of C was 0.048 mole L−1 sec−1  ENTER THE LETTER CORRESPONDING TO YOUR SELECTION IN THE SPACE PROVIDED. The numerical value of k, the rate constant, for this reaction is closest to a. 3 × 10−3b. 1 × 10−2c. 8 × 10−1d. 4 × 100e. 3 × 102 Which is the label for k, the rate constant?a. L2 mol−1 sec−1b. L2 mol−2 sec−1c. L2 mol−2sec−2d. L mol−1 sec−1e. mol2 L−2 sec−1 16. When [B] decreases 0.4 M, what will be the value of [A]?a. 1.6 Mb. 3.6 Mc. 0.8 Md. 2.8 Me. 3.4 M 17. Which of the following describes how the rate for this trial reaction, at constant temperature, changes as [B]approaches 0.4 mol L−1? a. The rate remains the same because the rate constant remains the same.b. The rate remains the same because the temperature remains the same.c. The rate decreases because the concentration of the reactants decreases.d. The rate decreases because the concentration of the products increases.e. The rate remains the same because the energy of activation remains the same.

The following 3 questions refer to the popular demonstration called “Elephants Toothpaste” in which the mechanism isbelieved to be: Step 1: H2O2 + I− → H2O + OI−Step 2: H2O2 + OI− → H2O + O2 + I− ENTER THE LETTER CORRESPONDING TO YOUR SELECTION IN THE SPACE PROVIDED. Identify the catalyst.a. O2b. OI−c. I−d. H2Oe. H2O2 Identify the intermediate:a. O2b. OI−c. I−d. H2Oe. H2O2 Which chemical equation is consistent with the mechanism provided?a. ½ H2O2 + I− → H2O + OI− + O2b. ½ H2O2 + I− → H2O + O2c. 2H2O2 → 2H2O + OI− + O2d. 2H2O2 + I− → 2H2O + O2e. 2H2O2 → 2H2O + O2

For the rate law, Rate= k[Q]2 [R]2,which statement is correct? ENTER THE LETTER CORRESPONDING TO YOUR SELECTION IN THE SPACE PROVIDED. a. The reaction is second order overall, and doublingboth the [Q] and [R] while keeping the temperatureconstant will lead to a 16-fold increase in the rate. b. The reaction is second order overall, and doublingboth the [Q] and [R] while keeping the temperatureconstant will lead to a bigger k and a 16-fold increasein the rate. c. The reaction is fourth order overall, and doublingboth the [Q] and [R] while keeping the temperatureconstant will lead to a bigger k and a 16-fold increasein the rate. d. The reaction is fourth order overall, and doublingboth the [Q] and [R] while keeping the temperatureconstant will lead to a 16-fold increase in the rate. e. The reaction is fourth order overall, and doublingboth the [Q] and [R] while keeping the temperatureconstant will lead to a bigger k and an 8-fold increasein the rate.
