Work, state property

Postby Adrian C 1D » Sun Jan 27, 2019 11:45 am

I understand that enthalpy is a state property and it is not dependent on the path taken to obtain that state. My notes also says that work is the opposite and is pathway dependent. What does this entail in terms of calculating it?

What this means is that you have to take into account intermediate steps when accounting for the total work performed rather than the total change between the initial and final states.

You would need to know the energy expenditure for each step of the reaction to get the total amount of work versus just calculating the net change when finding enthalpy.

This means that rather than being unconcerned with the way that the final product was created and with state functions like enthalpy, however with a nonstate function the process to achieve it actually matters in the calculations.
