Identify the incorrect statements among the following:
(a) All enthalpies of fusion are positive
(b) The magnitude of enthalpy change does not depend on the strength of the intermolecular interactions in the substance undergoing phase transformations.
(c) When a chemical reaction is reversed, the value of \(\Delta \mathrm{rH}^{\circ}\) is reversed in sign.
(d) The change in enthalpy is dependent of path between initial state (reactants) and final state (products)
(e) For most of the ionic compounds, \(\Delta_{\text {sol }} \mathrm{H}^{\circ}\) is negative
