###### Question:

Ethanol (C2H5OH) can be prepared by many different reactions including the two shown below: (2.1) C2H4 (g) + H20 (g) + C2H5OH (1) (2.2) C2H6 (g) + H20 (g) → C2H5OH (1) + H2 (g) Using the thermodynamic data below, calculate the change in the Gibbs free energy (in units of kJ) for reaction 2.1 at 298.15 K. AG; (kJ/mol) Sº (J/mol.K) 0 H2 (g) H2O (g) C2H5OH (1) C2H4 (g) -228.6 -174.9 68.0 AH; (kJ/mol) 0 -241.8 -277.7 52.5 130.6 188.8 160.7 219.6
