The decomposition of N 2 O 5 in CCl 4 at 318K has been studied by monitoring the concentration of N 2 O 5 in the solution. Initially the concentration of N 2 O 5 is 2.33 mol L –1 and after 184 minutes, it is reduced to 2.08 mol L –1 . The reaction takes place according to the equation: 2N 2 O 5 (g) → 4NO 2 (g) + O 2 (g) Calculate (i) the average rate of this reaction in terms of seconds and (ii) what is the rate of p
