Expert Answer
In formation of ammonia-
Oxidation state of N in N2 =0
Oxidation state of N in NH3 =-3
change in oxidation number of N in N2 in formation of NH3 =3
For 2 N atom = 6
So equivalent weight of N2 =28/6=14/3 g(molecular weight of N2 =28 g)
Equivalent weight of NH3= 17/3 g (molecular weight of NH3 =17 g)
Oxidation number change in H is =1 ( from 0 to +1)
so for two H atom in H2 =2
It means, equivalent weight of H2 = 2/1=2 g
