Enthalpy is equal to...

Enthalpy is equal to

A

`T^(2) [(del(G//T))/(delT)]_(P)`

B

`-T^(2) [(del(G//T))/(delT)]_(P)`

C

`T^(2) [(del(G//T))/(delT)]_(V)`

D

`-T^(2) [(del(G//T))/(delT)]_(V)`

Text Solution

Verified by Experts

The correct Answer is:
b
It can be derived that
`[ ( del(DeltaG//T))/(delT)] = - ( DeltaH)/(T^(2)) ` ( R efertopage)
or `DeltaH= - T^(2)[(del(DeltaG//T))/(delT)]_(P)`
This is one of theforms of Gibbs-Helmholtz equation.
