Answer #1

Sol :-

Given equations are :

H₂ + 2 N₂ + 5 O₂ ----------> 2 HNO₃ + 2 NO₂ , ΔH₁ = -202 KJ ................(1)

N₂H₄ ------------> 2 NH + H₂ , ΔH₂ = + 567 KJ .......................................(2)

2 N₂O₅ -----------> 2 N₂ + 5 O₂ , ΔH₃ = + 22.6 KJ ...................................(3)

Aim equation is :

N₂H₄ + 2 N₂O₅ ----------------> 2 HNO₃ + 2 NO₂ + 2 NH , ΔH = ? ................................(4)

Aim equation can be obtain by adding equations (1), (2) and (3). Because enthalpy is an additive property of the system, therefore Change in enthalpy of a reaction (ΔH) of the aim equation will by the sum of ΔH₁, ΔH₂ and ΔH₃.

So,

ΔH = ΔH₁ + ΔH₂ + ΔH₃

ΔH = - 202 KJ + 567 KJ + 22.6 KJ

ΔH = + 387.6 KJ

Hence, Change in enthalpy of the reaction is = + 387.6 KJ
