Consider the following liquid - vapour equilibrium Liquid iff VapourWhich of the following relations is correct

Answer»

`(dlnG)/(dT^(2))=(DeltaH_(V))/(RT^(2))`
`(dlnP)/(dT)=(-DeltaH_(v))/(RT)`
`(dlnP)/(dT^(2))=(-DeltaH_(v))/(T)`
`(dlnP)/(dT)=(DeltaH_(v))/(RT^(2))`

Solution :CLAUSIUS - Clapeyron's EQUATION
`(dlnP)/(dT)=(DeltaH_(v))/(RT^(2))`
