The following gas phase reaction produces ethanol (C2H;OH) by catalytic hydrogenation of acetaldehyde (CH;CHO). The reaction reaches equilibrium at a temperature of T= T(N) T(N) (°C) and a pressure of 3 bar: 484 CH;CHO (g)+ H, (g)→ C,H,OH (g) The reactive system initially contains 1.5 moles of Hydrogen (H2) for each mole of acetaldehyde (CH3CHO). The mixture is assumed to be an ideal gas. T(N) is the temperature corresponding to the student number as shown in the attached Table 4.1 (a) At the equilibrium conditions of temperature and pressure: (i) Determine AG° (kJ/kmol) and AH° (kJ/kmol) of the reaction. (ii) Calculate the equilibrium constant at standard condition of temperature, K(298.15K). (iii) Assuming that the heat of reaction, AHº, does not change with temperature, calculate the equilibrium constant, K(Tn), at the temperature T(N).
