Question
Please help!! I will raise the points if you feel it is necessary! Thanks in advance!!!
The table to the right gives the concentrations of NO2(g) as a function of time at a certain temperature for the following reaction NO2(g) N0(g)+^1/2 o2(g) Determine the order of this reaction by graphing first and secord order plots using the data provided. Order of reaction Number Input the value of the rate constant below and select the correct units. Ms-1 s-1 M-1 s-1 M-2 s-1 Number [NO2] (M) time (s) 0.0831 0.0 0.0666 4.9 0.0567 9.2 0.0497 13.3 0.0441 17.5
Explanation / Answer
order = 0
[A] = [Ao] - kt
k = ([A0] - [A])/t
= (0.0831 - 0.0666)/4.9
= 0.00336
units = M s -1 (first option)
