The given process is exothermic.
In the reaction \( N_2O_5(g) + H_2O(l) \rightarrow 2HNO_3(l) \), the change in enthalpy (\( \Delta H \)) is negative (\( -18.3 \) kcal), indicating that energy is released during the reaction. This characteristic is typical of exothermic reactions, which release heat to the surroundings.
