When a reaction invoives gases, the pressure of the system often changes as the reaction progresses. Chemists can monitor this pressure change. For exampie, consider the decomposition of dinitrogen pentoxide, shown in the foiiowing chemicai reaction.

The first step in understanding how a given chemical reaction occurs is to determine the form of the rate law. In this section we will explore ways to obtain the differential rate law for a reaction. First, we will consider the decomposition of dinitrogen pentoxide in carbon tetrachloride solution ... 

Another way to determine the instantaneous rate for a chemical reaction is to use the experimentally determined rate law, given the reactant concentrations and the specific rate constant for the temperature at which the reaction occurs. For example, the decomposition of dinitrogen pentoxide (N2O5) into nitrogen dioxide (NO2) and oxygen (O2) is given by the following equation. 

If the progress of a reaction causes a change in the total number of moles of gas present, the change in pressure of the reaction mixture (held at constant temperature and constant volume) lets us measure how far the reaction has gone. For instance, the decomposition of dinitrogen pentoxide, N205(g), has been studied by this method.

The experimental rate equations for some reactions have forms that are equivalent to those expected for unimolecular and bimolecular reactions but they do not correspond to the stoichiometry. For example, in Section 5.3.1 we established that the gas-phase thermal decomposition of dinitrogen pentoxide (Equation 5.1)...
