3. For the reaction 2NO2 ----> 2NO + O2
Rate = 1.4 * 10^-10 M*s [NO2]2 at 25.0 C.
If 2 mol of NO2 are initially present in a sealed 1.00 liter vessel at 25 C, what is the concentration of NO2 after 140 years?
I got 0.894 M.

stanfordream, for that question, doesn't it already tell you k (1.4 * 10^-10?). Also, it doesn't tell you the concentration of NO2, so how can you solve for k?
