For the reaction
`N_(2)(g) + 3H_(2)(g) rarr 2NH_(2)(g)`
Which of the following is correct?

A

`DeltaH = DeltaU`

B

`DeltaH gt DeltaU`

C

`DeltaH lt DeltaU`

D

`DeltaH = 2 DeltaU`

Text Solution

Verified by Experts

The correct Answer is:
c
`Deltah = DeltaU + DeltanRT`
`Deltan = (2-4) =- 2`
`:. DeltaH = DeltaU - 2RT`
or `DeltaU = DeltaH +2RT`
