Main Question or Discussion Point
Calculate ΔH for 2 mols of Nitrogen for the following transformation:
1 bar, 21°C → 200 bar, 21°C
Given that molar Cp = 4R
2. The attempt at a solution
How am I supposed to find the ΔH? From what I learned, there can only be a change in enthalpy when there's a change in temperature.
So the change in enthalpy will always be zero for an isothermal expansion.
