TReview lopicS] TRelerences 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 69.0 s, the concentration decreased to 0.1067 mol/L. What is the average rate of decomposition of NO2 during this time interval in mol/(L-s)? Average rate = mol/(L-s)

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
