Cоnsider the reаctiоn аnd its rаte law given belоw 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.
