what is the vaporisation enthalpy of water for a pressure of 500kPa ?

Expert Solution

Answer Enthalpy of vaporisation of water at 500 kPa = 37.66 KJ/mol

Using clausius clapeyron equation, the boiling point of water at 500 kPa is calculated to be 425 K

Using watson equation, the heat of vaporisation of water at 425 K is calculated

knowing the critical temperature of water is 647 K.

The enthalpy of vaporisation of water at a pressure of 500 kPa is found to be = 37.66 KJ/mol

Enthalpy H is a measure of the energy content of a system at constant pressure. Chemical reactions involve changes in enthalpy, ΔH, which can be measured and calculated: ΔHrxn∘=∑productsmΔHf∘−∑reactantsnΔHf∘ where the subscript "rxn" is for "enthalpy of reaction" and "f" is for "enthalpy of formation" and m and n represent the appropriate stoichiometric coefficients for each substance. The following table lists some enthalpy of formation values for selected substances. Substance ΔHf∘ (kJ/mol) NaOH(aq) −469.1 MgCl2(s) −641.8 NaCl(aq) −407.3 Mg(OH)2(s) −924.5...
