Question

The decomposition of NO2 (g) occurs by the following bimolecular elementary reaction:

2NO2 (g) --> 2NO (g) + O2 (g)

The rate constant at 273 K is 2.3 x 10^-12 L/mol x s, and the activation energy is 111 kJ/mol. How long will it take (in seconds) for the concentration of NO2 (g) to decrease from an initial partial pressure of 2.6 atm to 1.3 atm at 500. K? Assume ideal gas behavior and fixed volume of reaction vessel.
