For the reaction
`N_(2)(g) + 3H_(2)(g) hArr 2NH_(3)(g), DeltaH=?`

A

`Delta E- RT`

B

`Delta E- 2RT`

C

`Delta E + RT`

D

`Delta E + 2RT`

Text Solution

Verified by Experts

The correct Answer is:
B

`N_(2(g)) + 3H_(2(g)) hArr 2NH_(3(g))`
`Delta H= Delta E+ Delta n_(g) RT`
`Delta n= n_(p)- n_(r)= 2- 4= -2`
`therefore Delta H= Delta E- 2RT`
