3.) NO2 decomposes to yield NO and O2 according to the equation given below. The reaction
is second order with respect to NO2.
NO2 (g) → NO (g) + 02 (g)
a. If k has a value of 755 M- secl at 603 K and 4020 M-1 secl at 652 K, using the
Arrhenius equation, calculate the activation energy and the frequency factor.
b. Assuming that you start with a 1.0 M concentration of NO2 at 603K, what is the half-
life of NO2? How long will it take until only one fourth of the NO2 remains?
