The dinitrogen pentoxide (NOs) is a solid at room temperature. At a relative low temperature (320 K) it sublimates, and if the temperature keeps increasing beyond 600 K, it decomposes according to the equation: 2 N205 (g) - 02 (g) + 4 NO2 (g) A study of this reaction yielded the following results:

t/sec 0 1 2 3. 4. 5

[N205] /(molL-1) 0.500 0.301 0.163 0.103 0.059. 0.030

a) Using a graphical method, and assuming the reaction follows simple kinetics (either Oth, 1st or 2nd order), determine the reaction order.

b) Determine the rate constant for the reaction.

c) How long will it take to consume 75% of the reactant?

d) Calculate the partial pressure of NO2 after 1.50 seconds. NOTE: Include the graph(s) in your answer.
