Exothermic & endothermic
WebJun 16, 2024 · If you search for "standard enthalpy of formation hydrogen iodide", you get positive value $\pu{26.5 kJ/mol}$, what means the reaction is endothermic, as by convention, the values for elements in their standard state is zero. The other one is strongly endothermic, what you realize, if you search the same for nitric oxide.
