The average CH bond energy in CH4 is 415 kJ/mol. Use Table 9.2 (p. 371) and the
Chapter 9, Problem 9.87(choose chapter or problem)
The average CH bond energy in CH4 is 415 kJ/mol. Use Table 9.2 (p. 371) and the following to calculate the average CH bond energy in ethane (C2H6; CC bond), in ethene (C2H4; CC bond), and in ethyne (C2H2; CC bond): C2H6(g) 1 H2(g) 2CH4(g) DH8rxn 5 2265.07 kJ/mol C2H4(g) 1 2H2(g) 2CH4(g) DH8rxn 5 2202.21 kJ/mol C2H2(g) 1 3H2(g) 2CH4(g) DH8rxn 5 2376.74 kJ/mol
