The total energy required to dissociate one mole of gaseous methane (CH4) into gaseous atoms is 1664 kJ/mol. Calculate the average C-H bond energy.
Q1. The total energy required to dissociate one mole of gaseous methane (CH4) into gaseous atoms is 1664 kJ/mol. Calculate the average C-H bond energy.
Answer: 416
Explanation: Methane has four C-H bonds; 1664 kJ/mol divided by 4 yields 416 kJ/mol per bond. 436 is the bond energy of H-H molecules.
