Re: delta H vs q
Delta H is the change in enthalpy, while q is just heat, so it doesn't represent a change.

Re: delta H vs q
In some cases, such as that of delta U, particularly in biological reactions, qp and delta H can be equal because the there is not work due to expansion, meaning that delta U=delta H.

Re: delta H vs q
Change in enthalpy (delta H) is the amount of heat (q) absorbed or released at constant pressure.

Why is this? How does keeping the pressure constant equal to enthalpy? Thanks!
