Consider the following reactions:
`C(s)+O_(2)(g)toCO_(2)(g)+x " kJ"`
`CO(g)+(1)/(2)O_(2)(g)toCO_(2)(g)+y" kJ"`
The heat formation of CO(g) is :

A

`-(X+Y)kJ//mol`

B

`(X-Y)kJ//mol`

C

`(Y-X)kJ//mol`

D

`(Y+X)kJ//mol`

Text Solution

Verified by Experts

The correct Answer is:
C
`T.R:C_(s)+(1)/(2)O_(2(g))toCO_((g)),DeltaH_(r)=DeltaH_(f)`
`T.R=(I)+(II)rev`
`=(-X)+(+Y)`
`DeltaH_(r)=Y-X`
