1) The standard reaction enthalpy of the reaction between Methane and Dichloride to form Chloromethane and Hydrogen chloride is -114 kJ/mol. Knowing that the standard entropy change is 11.1 J/K·mol, calculate the variation of the standard Gibbs free energy at standard conditions, and tell wheter the reaction is spontaneous or not.
3)Explain how the temperature varies with the spontaneity of a reaction
chemistry which ΔHº < 0 and ΔSº < 0, assuming that both figures remain
constant with temperature variation .
2) Determine the variation of Enthalpy and Entropy for the combustion of Ethanol. Knowing that: Hfº(kJ/mol)=> Ethanol(l) = -277.7 CO2= -393.5 H2O= -285.8 Sfº(kJ/K·mol)=> Ethanol= 160.7 CO2(g)=213.6 O2= 205 H2O= 69.9
4) Would you recommend (from the standpoint of thermodynamics) obtaining Benzene from Acetylene at 298.15 K?
