Consider the following reaction:
2 NO2 (g) → 2 NO (g) + O 2 (g) rate = k [NO 2]2
When the initial concentration of NO2 is 100 mM, it takes 55 s for 90% of the NO 2 to react. Calculate the rate constant.
a) 0.042 mM–1·s–1
b) 1.8 x 10–5 mM–1·s–1
c) 1.6 mM–1·s–1
d) 1.6 x 10–3 mM–1·s–1
e) 0.13 mM–1·s–1
