2NO + O2 → 2NO2
Nitrogen monoxide and oxygen are prepared and mixed by setting up an apparatus with two glass bottles. As soon as the gases mix, a deep brown gas is formed.
During the reaction, underpressure is built up in the bottles. This can be explained, because from three molecules of gas only two molecules of reaction product are formed. Further decrease of pressure occurs, due to the following equilibrium in which the number of product molecules even decreases further:
2NO2 ↔ 2N2O4
