Question- Two salts, A and B react to form AB. The free energy of formation of A= -1030 kJ/mol and fro B= -840 kJ/mol and for the product, AB=-2150kJ.mol
I found ?G=-280 kJ/mol but I don't know to find the change in enthalpy. The question states that the overall change from A and B to AB in the order of the system is negligible. Does this imply an entropy change, ?S, of 0 which would make the ?H=?G?
