C(2)H(6(g)) + 3.5 O(2(g)) rarr 2CO(2(g))...

`C_(2)H_(6(g)) + 3.5 O_(2(g)) rarr 2CO_(2(g)) + 3H_(2)O_((g))`
`Delta S_("vap") (H_(2)O,l) = x_(1) " cal" K^(-1)` (boiling point is `T_(1)`)
`Delta H_(f) (H_(2)O, l) = x_(2), Delta H_(f) (CO_(2)) = x_(3), Delta H_(f) (C_(2)H_(6)) = x_(4)` Hence `Delta H` for the reaction is

A

`-295.96KJ`

B

`+295.96KJ`

C

`-296.04KJ`

D

`-296.32KJ`
