For the reaction,
`A(s)+3B(s)to4C(s)+D(l)`
`DeltaH` and `DeltaU` are related as-

A

`DeltaH=DeltaU`

B

`DeltaH=DeltaU+3RT`

C

`DeltaH=DeltaU+RT`

D

`DeltaH=DeltaU-3RT`

Text Solution

Verified by Experts

The correct Answer is:
A

`DeltaH=DeltaV+Deltan_(g)RT`
`A(s)+3B(g)to4C(s)+D(l)`
`Deltan_(g)=0-3=-3`
`DeltaH=DeltaU-3RT`
