Nitrogen dioxide, NO2, decomposes upon heating to form nitric oxide and oxygen according to the following equation: 2NO2(g)---->2NO(g) + O2(g)
At the beginning of an experiment, the concentration of nitrogen dioxide in a reaction vessel was 0.1103 mol/L. After 60.0 sec, the concentration decrease to 0.1076 mol/L. What is the average rate of decomposition of NO2 during this time interval, in mol/(L sec)?
