3) nitrogen dioxide decomposes to nitric oxide and oxygen via the reaction: In a particular experiment at 300 c, [no2] drops from 0. 0100 to 0. 00650 m in 100 s. the rate of disappearance of no2 for this period is __________ m/s. Answer: 3. 5 10-5: the rate law of a reaction is rate = k[d][x]. The units of the rate constant are __________. The data in the table below were obtained for the reaction: A + b p: the rate law for this reaction is rate = __________. Answer: k[a]2: the magnitude of the rate constant is __________. 2no2 2no + o2 follows second-order kinetics. At 300 c, [no2] drops from 0. 0100 m to 0. 00650 m in 100. 0 s. The rate constant for the reaction is __________ m-1s-1. At 230. 3 c, k = 6. 29 10-4s-1. [ch3nc] is __________ after 1. 000 103 s. Answer: 5. 33 10-4: a compound decomposes by a first-order process. 60. 0 minutes, the half-life of the compound is __________.
