Question

25. The reaction 2 NO2(g) + O3(g)  N2O5(g) + O2(g) was studied at a certain temperature with the following results:

 
Experiment [NO2(g)] (M) [O3(g)] (M) Rate (M/s)
 
1 0.502 0.502 21600
2 0.502 1.00 43100
3 1.00 0.502 43100
4 1.00 1.00 85800




(a) What is the rate law for this reaction?

Rate = k [NO2(g)] [O3(g)]
Rate = k [NO2(g)]2 [O3(g)]  
Rate = k [NO2(g)] [O3(g)]2
Rate = k [NO2(g)]2 [O3(g)]2
Rate = k [NO2(g)] [O3(g)]3
Rate = k [NO2(g)]4 [O3(g)]






(b) What is the value of the rate constant?





(c) What is the reaction rate when the concentration of NO2(g) is 0.505 M and that of O3(g) is 1.37 M if the temperature is the same as that used to obtain the data shown above?

______ M/s
