Given, NH(3)(g) + 3Cl(2)(g) NCl(3)(g) ...

Given,
`NH_(3)(g) + 3Cl_(2)(g) NCl_(3)(g) + 3HCl, -DeltaH_(1)`
`N_(2)(g) + Cl_(2)(g) to 2NH_(3)(g),-DeltaH_(2)`
`H_(2)(g) + Cl_(2)(g) to 2HCl_(g),-DeltaH_(3)`
The heat of formation of `NCl_(3)(g)` in the terms of `DeltaH_(1), DeltaH_(2)` and `DeltaH_(3)` is

A

`Delta_(r)H = -DeltaH_(1) + (DeltaH_(2))/2 -3/2 DeltaH_(3)`

B
