Consider that the first order decomposition reaction of N2O5 written as -
2N2O5 (g) ➡ 4NO2 (g) + O2 (g) ; rate = k[N2O5]
N2O5(g) ➡ 2NO2 (g) +1/2 O2 (g) ; rate = k'[N2O5]
Find the relation between k and k'.

Hi,2N2O5 (g) →4NO2g + O2g , Rate = kN2O5 N2O5 (g) →2NO2g + 12O2g,  Rate = k'N2O5Rate of disapperance of N2O5 ,  12-dN2O5dt  =kN2O5   
 for first reactionRate of disapperance of N2O5 , -dN2O5dt  =k'N2O5 
 for second reactionRate of disapperance of N2O5 for first reaction =Rate of disapperance of N2O5for second reactionSo, we take k =2k'Regards
