The rate of decomposition rate of nitrogen (V) of the oxide at 55*C by the reaction: 2N2O5 = 4NO2 + O2 is 1.7*10^-3. 5 liter capacity added 2 mol of nitrogen (V) oxide. Calculate the rate of reaction at the moment when in the reaction mixture: a). 0.1 mol of oxygen is formed; b). 0.1 mol of nitrogen (IV) oxide is formed; c). will remain 0.1 mol of nitrogen (V) oxide?
