Re: Delta H
I would have to see an example of a problem but if it is a reversible, isothermal process and temperature is constant, then Delta H would be 0 in all cases because there would be no heat transfer in and out of the system.

But this is only for when pressure is constant right?

Re: Delta H
You would need to use the delta H equation and work with what you are given in the problem, mainly find what is constant and manipulate the equation to reflect that while looking for delta H.

Re: Delta H
You can find delta H either through products minus reactants, or Hess's law, or the Gibbs free energy equation delta G = delta H - T delta S
