For the reaction
`C_(3)H_(8)(g) + 5 O_2)(g) rightarrow 2CO_(2)(g) + 4 H_(2)O(l)` at constant temperature , `DeltaH - Delta E` is`

A

`-RT`

B

`+RT`

C

`-3RT`

D

`+3RT`

Text Solution

Verified by Experts

The correct Answer is:
C
`Delta H- Delta E= Delta n_(g)RT , Delta n_(g)= -3`
So, `Delta H- Delta E= - 3RT`
