(a) Interpretation: The compound that is soluble in water among naphthalene (C 10 H 8 ) or hydrogen peroxide (H-O-O-H) should be identified. Concept introduction: Solubility depends on the solvent and solute having same intermolecular bonds. Hence, the polar compounds are soluble in a polar solvent and nonpolar compounds are soluble in non-polar solvents.

In the decomposition reaction in solution B → C, only species C absorbs UV radiation, but neither B nor the solvent absorbs. If we call At the absorbance measured at any time, A0 the absorbance at the beginning of the reaction, and A∞ the absorbance at the end of the reaction, which of the expressions is valid? We assume that Beer's law is fulfilled.
