Question

What is difference between ∆H and ∆H°.

Answer 1

Answer:

You can say that Q (Heat) is energy in transit. Enthalpy (Delta H), on the other hand, is the state of the system, the total heat content. They both can deal with heat (qp) (Q at constant pressure) = (Delta H) but both Heat and Enthalpy always refer to energy, not specifically Heat.
