What will be the enthalpy of formation of carbon to produce carbon monoxide on the basis of data given below:
`C_((s))+O_(2(g))rarrCO_(2(g))-393.4kJ`
`CO_((g))+(1)/(2)O_(2(g))rarrCO_(2(g))-283.0kJ`

A

`+676.4kJ`

B

`-676.4kJ`

C

`-110.4kJ`

D

`+110.4kJ`

Text Solution

Verified by Experts

The correct Answer is:
C
`C+(1)/(2)O_(2) rarr CO` is obtained by (i) - (ii).
`-393.4-(-283.0)=-110.4kJ`
