Consider a unary system of water from 200->500 K at P = 1 atm. Some properties of water in solid, liquid, and gaseous phase are given below: S (298 K) = 70 J mol K-1 Cp = 38 Jmol ' K-1 = 75 J mol 1 K-1 CG = 34 Jmol ' K-1 AHS-L(273 K) = 6kJ mol-1 AHL-G(373 K) = 41 kJ mol-1 (a) Using the information provided above, answer the following questions: i. Choose 298 K as the reference, set the chemical potential of the equilibrium phase (liquid phase) as 0, calculate the enthalpy of liquid water using the following equation: H = G =H -TS ii. Calculate the entropy and enthalpy of solid water at the melting temperature Tm = 273 K and the entropy and enthalpy of gaseous water at boiling temperature To = 373K using the following equations: SS(Tm) = S'(298 K) + AHS-L(I'm) J298 K T I'm To SG(To) = SL (298 K) + Cedr + AHL-G(To) 298 K T To I'm HS(Tm) = HL(298 K) + ObdT - AHS-L(Im) 298 K H(To) = HL (298 K) + ObdT + AHL - G (To ) 298 K Assume that the constant pressure heat capacity in this temperature range can be considered as constant
