In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K N2O5(g) 2 NO2(g) + ½ O2(g) the concentration of N2O5 was followed as a function of time. It was found that a graph of In[N,05] versus time in seconds gave a straight line with a slope of -6.82x103 s and a y-intercept of -2.58 . Based on this plot, the reaction is first order in N205 and the half life for the reaction is seconds.
