Energetics Definitions

Enthalpy ­ The heat content of a system measured at a constant pressure. H = (enthalpy of
products) ­ (enthalpy of reactants)

Standard enthalpy ­ Heat content of a system measured at 100kPa and 298K (Standard
conditions) . Cannot be measured directly so must measure the enthalpy change.…

PSA

Hydration of anhydrous copper sulphate

Cannot measure this equation easily

CuSO 5H
4+ -> CuSo
2O
4.5H2O



So use 2 enthalpy changes

Make

CuSO aq -> CuSO
4+ 4 (aq)


Also make CuSO4.
H +aq -> CuSO
2O…
