question

Gaseous hydrochloric acid dissociates in water as described bythe following chemical reaction : HCl(g) \rightarrow H^+(aq) +Cl^-(aq) Using the following heats of formation, calculate \DeltaH°_77°F for thereaction. Heats of formation @ 77°F HCl-\DeltaH_f= - 87.54 Btu/mole H^+ -\DeltaH_f= 0 Btu/mole Cl^- -\DeltaH_f= - 158.8 Btu/mole
