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)
Step 1

Rate of reaction is calculated using the given formula,
