Conversion of sulphur to SO(3) has Delta...

Conversion of sulphur to `SO_(3)` has `Delta H = -2x Kcal` and conversion of `SO_(2)` to `SO_(3)` involves `DeltaH = -ykcal`. The correct thermochemical equation for formation of `SO_(2)` is

A

`S+O_(2)rarrSO_(2)DeltaH=(y-2x)`

B

`S+O_(2)rarrSO_(2)DeltaH=-(y-2x)`

C

`S+O_(2)rarrSO_(2)DeltaH=(x+y)`

D

`S+O_(2)rarrSO_(2)DeltaH=2y-3x`

Text Solution

Verified by Experts

The correct Answer is:
A
`S_((s))+(3)/(2)O_(2(g))rarrSO_(3(g)),-2x`
`SO_(2(g))+(1)/(2)O_(2(g))rarrSO_(3(g)),-y`
