What is the relationship between a strong acid's chemical nature and amount of heat released when react w/base

Question

Example would be HCl reacting with NaOH. It may have something to do with whether the acid is monoprotic or diprotic.

Answer 1

The stronger acid/base combination the more heat released in reaction.

For many acid/base reactions you make H2O. The less energy needed to ionize that H+ or OH- the more left over as heat released.

HA ->H+ + A- delHA=energy to make H+
BOH -> B+ + OH- delBOH=energy to make OH-

H+ + OH- -> H2O delH2O= heat of formation of water - delHA - delBOH

more negative delHA and delBOH are the greater delH2O is.
