The rate of decomposition of N2O5 in CCl4 at 323 K has been studied by monitoring the concentration of N2O5 in the solution. - 2 N2O5(9) 4 NO2(g) + O2(g) Initially the concentration of N2O5 is 2.35 M. At 173 minutes, the concentration of N2O5 is reduced to 2.17 M. Calculate the average rate of this reaction in M/min. 0.00104 X M/min Tutorial Did you recall that the average rate of change of a substance is the change in concentration of the substance divided by the time required for that concentration change? Did you recall how to account for the average rate of change of reactants versus products? Did you recall how to account for the coefficients of the reactants and products when calculating rates?
