Step 1

As per the Hesss law of Constant heat Summation, regardless of the number of steps or stages that have taken place for a given chemical reaction, the total change in the enthalpy for a given chemical reaction is the sum of all the changes.

Step 2

The given reactions are as follows:

Step 1-2H, (g)+N, (g)>N,H (g)
ΔΗ
= 95.4 kJ
AH 187.6 kJ
+ ΝH, (g)
Step 2 -N,H(g)+H2 (g)
