Solution

In the following reaction:
2NH3N2+3H2
The equivalent weight of NH3 is =Molecularweighty
The formula for the equivalent mass is as given below.
Equivalent mass =Formula massTotal change in the oxidation number of an element per molecule that undergoes oxidation or reduction

The oxidation number of N changes from 3 to 0.
The change in the oxidation number of N per ammonia molecule is 3.
Hence, the value of y is 3.
