Nitrogen dioxide, NO2, decomposes upon heating to form nitric oxide and oxygen according to the following equation: 2NO2(9) → 2NO(9) + O2 (g) At the beginning of an experiment, the concentration of nitrogen dioxide in a reaction vessel was 0.1103 mol/L. After 63.0 s, the concentration decreased to 0.1059 mol/L. What is the average rate of decomposition of NO2 during this time interval in mol/(L·s)? Average rate = mol/(L-s)

Question
Nitrogen dioxide, NO2, decomposes upon heating to form nitric oxide and oxygen according to
the following equation:
2NO2(9)
+ 2NO(9) + O2(g)
At the beginning of an experiment, the concentration of nitrogen dioxide in a reaction vessel was
0.1103 mol/L. After 63.0 s, the concentration decreased to 0.1059 mol/L. What is the average
rate of decomposition of NO2 during this time interval in mol/(L·s)?
Average rate =
mol/(L-s)
