Question

Ammonium nitrite, NH4NO2, is the ammonia salt of nitrous acid and it is used in explosives. It will decompose quicker when dissolved in an aqueous solution and the reaction is
NH4NO2 → N2+ 2H2O
A laboratory staff has done the kinetic study of the decomposition of ammonium nitrite and the observations made by him are listed in Table 1.
Time (s) Concentration of ammonium nitrite (moles/litre)
0 0.073
600 0.0548
1200 0.0412
1800 0.0304
2400 0.0234
3000 0.0172
3600 0.01280
1.1 Identify the order of the reaction using graphical method 1.2 Calculate the rate constant of this reaction 1.3 Calculate the half-life of the reaction 1.4 Comment on the relationship between the initial concentration of the reactant and the half-life of this reaction
