The enthalpy of solution for naoh is -45 kj/mol. What can be concluded about the relative magnitudes of the absolute values of δhsolute + δhsolvent and δhmixing ? δhsolute is the heat associated with separating the solute particles, δhsolvent is the heat associated with separating the solvent particles, and δhmixing is the heat associated with mixing the solute and solvent particles.
