The rate of the reaction was studied at a certain temperature. O(g) + NO2(g) NO(g) + O2(g) (a) In the first set of experiments, NO2 was in large excess, at a concentration of 1.0 ✕ 1013 molecules/cm3 with the following data collected. Time (s) [O] (atoms/cm3) 0 5.0 ✕ 109 1.0 ✕ 10-2 1.9 ✕ 109 2.0 ✕ 10-2 6.8 ✕ 108 3.0 ✕ 10-2 2.5 ✕ 108 What is the order of the reaction with respect to oxygen atoms? zero order half order first order second order third order Correct: Your answer is correct. (b) The reaction is known to be first order with respect to NO2. What is the overall rate law? chemPadHelp rate = k . [O] . [NO2] rate = k . [O] . [NO_2] Correct. Determine the value of the rate constant. WebAssign will check your answer for the correct number of significant figures. 3 100.15 Incorrect: Your answer is incorrect. cm3/molecules·s
