For the combustion reaaction at `298K` , `H_(2)(g)+1//2O_(2)(g)rarrH_(2)O(l)`
Which of the following alternetive (s) is/are correct ?

A

`DeltaH=DeltaE`

B

`DeltaH gt DeltaE`

C

`DeltaH lt DeltaE`

D

`DeltaH` & `DeltaE` have no relation with each other

Text Solution

Verified by Experts

The correct Answer is:
C
`Deltan=-1//2-1=-3//2`
Since, `Deltanlt0`
`:.DeltaH` is `lt DeltaE`
