O-chlorobenzaldehyde + sodium sulfite + catalyst yield o-sulfonic benzoaldehyde; the reaction takes place at atmospheric pressure and at a temperature of 140°C. Is this reaction exothermic or endothermic?

Just check the enthalpy values of the reactants and products and do the calculation, and you’ll know!
