Enthalpy of so3

WebThe standard enthalpy change for the reaciton of SO3 (g) with H2O (l) to yield H2SO4 (aq) is ΔH° = -227.8 kJ. Use the information in Problem 9.104 to calculate ΔH°f for H2SO4 … WebEnthalpy is a state function, defined by the internal energy (E), the pressure (P) and volume (V) of a system: H = E + PV and ΔH = ΔE + Δ (PV) For enthalpy, there are no method to determine absolute values, only enthalpy changes (ΔH values) can be measured. Then it is important to have a common and well defined reference state.
