Bond enthalpy is the energy required to break a chemical bond between two atoms in a molecule. It can be used to determine heat transfer in chemical reactions and is expressed as kJ/mol. The breaking of the bond can occur via heterolysis or homolytic fission. Bond enthalpy also refers to the likelihood of a thermodynamic […]
Enthalpy is the exchange of thermal energy during chemical reactions, measured in kJ/mol. Exothermic reactions release heat, endothermic reactions absorb heat. Energy level diagrams and calorimeters are used to measure enthalpy change. Calculation requires knowledge of water’s specific heat capacity, mass, and temperature change. Enthalpy is the exchange of thermal energy that occurs during chemical […]
