Question

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 0.113 mol/L. After 60.0 s, the concentration decreased to 0.1076 mol/L. Whatt is the average rate of decomposition of NO2 during this time intervail in mol/(L * s)

can someone help me with this one too please

Answer 1

avg rate = delta C/delta T
delta C is change in concentration
delta T is change in time.

0.113-0.1076 = change in C in molarity.
60 sec = change in time.
divide for the answer.
