Using Appendix 2 in your textbook, what is the value for the standard change in Gibbs free energy (in kJ) at 25oC of the reaction: C2H4(g) + H2(g) --> C2H6(g)?
Standard Gibbs free energy of ethane,
= - 32.9 kJ/mol
Standard Gibbs free energy of ethylene,
= 68.2 kJ/mol
Standard Gibbs free energy of hydrogen,
= 0 kJ/mol
= - 32.9 - (68.2 + 0)
= - 101.1 kJ/mol
Therefore, the standard change in Gibbs free energy for the reaction = - 101.1 kJ/mol
