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

A

`DeltaH_(f)=-DeltaH_(1)+(DeltaH_(2))/(2)-(3)/(2) DeltaH_(3)`

B

`DeltaH_(f)=DeltaH_(1)+(DeltaH_(2))/(2)-(3)/(2) DeltaH_(3)`

C

`DeltaH_(f)=-DeltaH_(1)-(DeltaH_(2))/(2)-(3)/(2) DeltaH_(3)`

D

None

Text Solution

Verified by Experts

The correct Answer is:
A
`(1)/(2)N_(2)(g)+(3)/(2)Cl_(2)(g)rarr NCl_(3)(g)`
`DeltaH=-DeltaH_(1)+(DeltaH_(2))/(2)-(3)/(2)DeltaH_(3)`
