Question

For the reaction,2N2O5 (g)   4 NO2 (g)  + O2 (g) the rate of formation of NO2 (g)  is 2.8 x 10-3 Ms-1. Calculate the rate of disappearance of N2O5 (g).

Answer

2N2O5 (g)    4NO2 (g)  + O2 (g)Rate of reaction -12d[N2O5]dt = 14d[NO2]dt = d[O2]dtAccording to questiond[NO2]dt = 2.8 x 10-3 Ms-1-d[N2O5]dt = 24d[NO2]dt = 12 x 2.8 x 10-3 Ms-1 = 1.4 x 10-3 Ms-1
