Marks 19/19 Grade 10 out of a maximum of 10 ( 100 %) Question 1 Marks: 1 Initial rate of reaction data is given in the next question for the following reaction: 2A + B → C +D The rate of reaction = k[A] x [B] y . What are x and y, that is, what is the order of reaction with respect to A and B? Choose at least one answer. a. x =0 b. x = 0.5 c. x = 1 d. x = 2 e. y = 0 f. y = 0.5 g. y = 1 h. y = 2 No partial credit. All correct choices must be selected to get credit. Correct Marks for this submission: 1/1. Question 2 Marks: 1 Determine the rate constant from the concentration-time dependence (The units for the initial rate of reaction are Ms -1 ): [A] [B] Init. Rate 0.020 0.15 0.055 0.035 0.15 0.096 0.050 0.35 0.75
Answer: Correct Marks for this submission: 1/1. Question 3 Marks: 1 Consider the second-order decomposition of nitroysl chloride: 2NOCl(g) → 2NO(g) + Cl 2 (g) At 450 K the rate constant is 15.4 atm -1 s -1 . How much time (in s) is needed for NOCl originally at a partial pressure of 60 torr to decay to 13.8 torr? Answer:
