Solved: At 258C, the standard enthalpy of formation of
Chapter 6, Problem 6.118(choose chapter or problem)
At 258C, the standard enthalpy of formation of HF(aq) is given by 2320.1 kJ/mol; of OH2(aq), it is 2229.6 kJ/mol; of F2(aq), it is 2329.1 kJ/mol; and of H2O(l), it is 2285.8 kJ/mol. (a) Calculate the standard enthalpy of neutralization of HF(aq): HF(aq) 1 OH2(aq) F2(aq) 1 H2O(l) (b) Using the value of 256.2 kJ as the standard enthalpy change for the reaction H1 (aq) 1 OH2(aq) H2O(l) calculate the standard enthalpy change for the reaction HF(aq) H1 (aq) 1 F2(aq)
