Calculating Enthalpy Changes
... The shift to high pressure will shift the reaction further towards products. This is clear intuitively from Le Chatelier’s principle, but it is quantified using the equilibrium expressions we have learned. Since the free energy change is negative, this might seem unnecessary. However, the Haber-Bosc ...
