Calculate the enthalpy change when 2.38 ...

Calculate the enthalpy change when `2.38 g` of carbon monoxide `(CO)` vaporise at its normal boiling point.`Delta H_(vap) CO = 6.04kJmol^(-1)`

Text Solution

Verified by Experts

`DeltaH_("vap")CO=6.04 kJ mol^(-1)`
Mol. Mass of `CO=12+16=28 am u`.
Enthalpy change when `2.38 g` of `CO` vaporise at its normal boiling point
`=(6.04 kJxx2.38)/(28)`
`=(6.04xx2.38xx1000)/(28)J`
`= +513.4 J`
