$1\times{10}^{-5}\frac{M}{s}$

Explanation:

The stoichiometry for this reaction is

$2NO_2\rightarrow2NO+O_2$

The rate for this reaction can be written as

$-r_{NO_2}=-\frac{d\left[NO_2\right]}{dt}=\frac{(0.01-0.008)M}{100s}=2\times{10}^{-5}\frac{M}{s}$

This rate of disappearence of NO_2 can be realated to the rate of appearence of O_2 as follows (the coefficients of each compound are defined by the stoichiometry of the reaction)

$-r_{O_2}=-r_{NO_2}\times\frac{coefficient\ O_2\ }{coefficient\ NO_2}=2\times{10}^{-5}\frac{M}{s}\times\frac{1\ mole\ O_2\ }{2\ mole\ NO_2}=1\times{10}^{-5}\frac{M}{s}$
