If `Delta_(f)H^(@)(C_(2)H_(4))` and `Delta_(f)H^(@)(C_(2)H_(6))` are `x_(1)` and `x_(2)` K cal/mol, then heat of hydrogenation of `C_(2)H_(4)` is

A

`x_(1)+x_(2)`

B

`x_(1)-x_(2)`

C

`x_(2)-x_(1)`

D

`x_(1)+2x_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(2)H_(4)+H_(2)toC_(2)H_(6)DeltaH_("rxn")^(@)`
`DeltaH_("rxn")^(@)=DeltaH_(f)^(@)(C_(2)H_(6))-DeltaH_(f)`
`""^(@)(C_(2)H_(4))`
`=x_(2)-x_(1)`
