Delta H

[605110118]

How do you find the change in enthalpy for a reaction if you aren't given the values?

[Samuel G Rivera - Discussion 4I]

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.

Delta H can usually be written as q. This is derived from the equation . , so .

But this is only for when pressure is constant right?

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.

yes it is only when pressure is constant

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
