Does this bond formation release energy?

Click For Summary
SUMMARY

The bond formation between -NH2 and H+ to create NH3+ releases energy due to a decrease in enthalpy. This occurs when the enthalpy of the products (NH3+) is lower than that of the reactants (-NH2 and H+). The electrostatic interactions between the positively charged hydrogen ion and the negatively charged lone pair on the nitrogen atom contribute to this energy release, resulting in a decrease in potential energy during the reaction.

If -Nh2 terminal become Nh3+, is this bond formation release energy in terms of entalpy decreasing way?

Yes, if the enthalpy of the products is lower than the enthalpy of the reactants, the reaction will release energy (usually in the form of heat). Eletrostatic interactions between the positively-charaged hydrogen ion and slight negative charge on the lone pair of the nitrogen atom cause the decrease in potential energy when the two interact.
