1a) In a study of the gas phase decomposition of dinitrogen pentoxide at 335 K N2O5(g)2 NO2(g) + Â½ O2(g) the concentration of N2O5 was followed as a function of time. It was found that a graph of ln[N2O5] versus time in seconds gave a straight line with a slope of -6.72Ã10-3 s-1 and a y-intercept of -1.67 . Based on this plot, the reaction is [ ] order in N2O5 and the rate constant for the reaction is

1b) In a study of the rearrangement of cyclopropane to propene at 500 Â°C (CH2)3CH3CH=CH2 the concentration of (CH2)3 was followed as a function of time. It was found that a graph of ln[(CH2)3] versus time in seconds gave a straight line with a slope of -1.03Ã10-3 s-1 and a y-intercept of -2.83 . Based on this plot, the reaction is [ ] order in (CH2)3 and the half life for the reaction is
