N2 + 3H2 → 2NH3 Rate of production of NH3 is 0.001 kg/hr–1 then rate of decomposition of H2 will be :-
(1)    0.003 kg hr–1
(2)    0.007 kg hr–1
(3)    0.006 kg hr–1
(4)    0.00017 kg hr–1

Dear Student,

N2 + 3H2    2NH3Rate of reaction =12d[NH3]dt=-d[N2]dt=-13d[H2]dtNow, we have been given that rate of of production of NH3 i.e. d[NH3]dt= 0.001 kghr-1and, from above relation we can say that12d[NH3]dt=-13d[H2]dtor, -d[H2]dt=32d[NH3]dtor, d[H2]dt=32×0.001 kghr-1 =0.0015 kghr-1
