How do I (a) determine the energy change in the following reaction 2 O2 + CH4→ CO2 + 2 H2O given the following bond dissociation energies: C-C 340kJ/mol; C-H 420kJ/mol; O=O 490 kJ/mol; O-H 460 kJ/mol; C=O 720 kJ/mol. (b) Is the reaction exothermic or endothermic? Explaination?
Bond Parameters
Many factors decide the covalent bonding between atoms. Some of the bond parameters are bond angle, bond order, enthalpy, bond length, etc. These parameters decide what kind of bond will form in atoms. Hence it is crucial to understand these parameters in detail and understand how changing these parameters affects the kind of bonding or various characteristics.
Bond Dissociation Energy
The tendency of an atom to attract an electron is known as its electronegativity.
