Web Quiz 1 Question # 1 Which of the following statements best describes the condition(s) needed for a successful formation for a product according to the collision model? A. The collision must involve a sufficient amount of energy, provided from the motion of the particles, to overcome the activation energy. B. The relative orientation of the particles has little or no effect on the formation of the product. C. The relative orientation of the particles has an effect only if the kinetic energy of the particles is below some minimum value. D. The relative orientation of the particles must allow for formation of the new bonds in the product. E. The energy of the incoming particles must be above a certain minimum value and the relative orientation of the particles must allow for formation of new bonds in the product. Question # 2 The average rate of disappearance of ozone in the reaction 2O 3 ( g ) 3O 2 ( g ) is found to be 9.0 x 10 -3 atm over a certain interval of time. What is the rate of appearance of O 2 during this interval? A. 1.3 x 10 -2 atm/s B. 9.0 x 10 -3 atm/s C. 6.0 x 10 -3 atm/s D. 3.0 x 10 -5 atm/s E. 2.7 x 10 -5 atm/s Question # 3 The decomposition of N 2 O 5 ( g ) to NO 2 ( g ) and O 2 ( g ) obeys the first-order kinetics. Assuming the form of the rate law is Rate = - [N 2 O 5 ] / t = k [N 2 O 5 ] where k = 3.4 x 10 -5 s -1 at 25°C. What is the initial rate of reaction at 25°C where [N 2 O 5 ] 0 = 5.0 x 10 -2 M? A. 3.4 x 10 -5 mol/L · s B. 1.7 x 10 -6 mol/L · s C. 6.8 x 10 -4 mol/L · s D. 5.0 x 10 -2 mol/L · s
