Calculating enthalpy change from temperature data for three acid-base reactions
The problem says: Enthalpy is always reported with respect to a reactant. Calculate the enthalpy change, DeltaH, for each reaction in terms of kJ/mol for one of the reactants. (i.e either HCL or NaOH). I had three reactions: 1. NaOH + HCL---->H20 +NaCl 2.NH4Cl +NaOH---->H20 +NH3 +NaCl 3...- NickP717
