Question

 

Dinitrogen pentoxide (N2O5) decomposes as follows to nitrogen dioxide and nitrogen trioxide:

N2​O5​(g)NO2​(g)+NO3​(g)

Calculate the average rate of the reaction between consecutive measurement times in the following table. 
Time (s) [N2O5] (molecules/cm3)
 0.00 1.105×1012 
 1.95  1.040×1012 
3.90  9.93×1011 
5.85  9.58×1011 
7.80  9.33×1011 
 
Express every answer to two significant figures.
Rate 1 =     molecules/(cm3·s)   
 
Rate 2 =    molecules/(cm3·s)   
 
 
Rate 3 =    molecules/(cm3·s) 
 
 
Rate 4 =    molecules/(cm3·s)
