NH3(g) + 3Cl2(g)  NCl3(g) + 3HCl(g) ; -ΔH1
N2(g) + 3H2(g)  2NH3(g) ; ΔH2
H2(g) + Cl2(g)  2HCl(g) ; ΔH3
The heat of formation of NCl3 (g) in the terms of ΔH1, ΔH2 and ΔH3 is
  • a)
  • b)
  • c)
  • d)
     None
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
NH3(g) + 3Cl2(g)NCl3(g) + 3HCl(g) ; -ΔH1N2(g) + 3H2(g)2NH3(g) ; ...
The formation of NCl3 be like
½ N2 + 3/2Cl2 ⇋ NCl3
We can see that for this setup, we need to have eqn (ii) divided by 2, reversing eqn (iii) and multiplying it by 3/2 and then adding all these to equation (i).
So option a is correct.

None of these is the correct answer , bcuz the correct relation is like

∆Hf = -∆H¹ -H²/2 -3H³/2
