Concept explainers
Interpretation: An explanation corresponding to the given statement that the phase (solid, liquid or gaseous) for every compound in the reaction must be known in order to calculate the enthalpy change of a
Concept introduction: The energy which is required in a molecule to break one mole of a covalent bond in its gaseous phase is known as bond energy of that bond. It is expressed in terms of enthalpy change denoted by
To determine: An explanation corresponding to the given statement that the phase (solid, liquid or gaseous) for every compound in the reaction must be known in order to calculate the enthalpy change of a chemical reaction by using bond energies.
