C(2)H(6)(g)+3.5O(2)(g)to2CO(2)(g)+3H(2)O...

`C_(2)H_(6)(g)+3.5O_(2)(g)to2CO_(2)(g)+3H_(2)O(g)`
`DeltaS_("vap")(H_(2)O,l)=x_(1)" "cal K^(-1)` (boiling point`=T_(1)`)
`DeltaH_(f)(H_(2)O,l)" "=x_(2)`
`DeltaH_(f)(CO_(2))" "=x_(3)`
`DeltaH_(f)(C_(2)H_(6))" "=x_(4)`
Hence, `DeltaH` for the reaction is :

A

`2x_(3)+3x_(2)-x_(4)`

B

`2x_(3)+3x_(2)-x_(4)+3x_(1)T_(1)`

C

`2x_(3)+3x_(2)-x_(4)-3x_(1)T_(1)`

D

`x_(1)T_(1)+x_(2)+x_(3)-x_(4)`
