Calculate the difference between DeltaE ...

Calculate the difference between `DeltaE and DeltaH` for the following reaction at `27^(@)C` (in kcal)
`C("graphite")+2H_(2)(g)toCH_(4)(g)`

A

`-0.6`

B

`-1.2`

C

`+0.6`

D

`+1.2`

Text Solution

Verified by Experts

The correct Answer is:
C
`C("graphite")+2H_(2)(g) to CH_(4)(g)`
`DeltaH=DeltaE+Deltan_(g)RT`
`DeltaE-DeltaH=-Deltan_(g)RT`
`DeltaE-DeltaH=-(-1)xx2xx300`
`=600cal=0.6kcal`
