The difference in the values of Δ E for the given reactions is to be rationalized. Concept introduction: The bond energy is defined as the amount of energy which is required to break a chemical bond in a molecule or it is the measure of chemical bond strength. It depends on many factors like size of atoms which are involved in a reaction, electron affinities , electronegativity differences and the structure of the molecule. For a shorter bond length the value of bond energy is higher. To determine: The differences in the values of Δ E for the given reactions.

At the end of the silica gel production process, color changes occur during drying. Explain these color changes.
If CoCl2/H2O is dissolved in a mixture of H2O and concentrated HCl in a test tube, the tube is gently heated over a flame to approximately 80°C and then cooled externally. Explain the color changes that occur.
