About the calculation of thermodynamic properties of pure fluid, the error in the following statement is ().

A、

The enthalpy or entropy values obtained from vapor tables or charts of a pure substance from different sources are not necessarily the same

Because the residual function is the difference between the properties of two isothermal states, the residual function can not be used to calculate the change of properties with temperature

The thermodynamic basic formula dH=TdS+Vdp is only applicable to reversible processes

Ideal gas thermal tolerance Cp-Cv=R is also applicable to ideal gas mixtures
