Useful Data and Formulae: Cp water = 4.2 kJ kg-1 K-1 Specific volume of water at 35°C = 0.001006 m³ kg-1 Cp steam = 2.0 kJ kg-1 K-1. Enthalpy of vaporization of water at 100°C = 2257 kJ kg-1 Molar mass of water = 18.01 Density of steam at 175°C = 4.66 kg m3. Standard free energies of formation: Substance HCl(g) O2(g) Cl2(g) H2O(g) AG (kJ mol-1) -95.299 -228.59 QUESTION 1 (a) Write the thermochemical equation for the formation of 1 mole of solid sodium bicarbonate, NaHCO3(s), from its elements. (b) Use the following information to calculate the standard enthalpy of formation of NaHCO 3(s): (i) AH, of CO2(g) = - 393.51 kJ mol-1 (ii) AH, of NaOH(s) = -425.61 kJ mol-1 (iii) NaOH() +CO2(g) → NaHCO3{s) AH = -127.5 kJ mol¬
