The ESR spectrum for the radical 10 BH 3 is to be stated. Concept introduction: The full form of ESR spectroscopy is electron-spin resonance spectroscopy. The ESR spectroscopy is used to observe those materials which contain unpaired electrons. ESR spectroscopy also works like NMR spectroscopy, but, in ESR, electron spin in spite of atomic nuclei spin gets excited.

Question

Use the observations about each chemical reaction in the table below to decide the sign (positive or negative) of the reaction enthalpy AH and reaction entropy AS. Note: if you have not been given enough information to decide a sign, select the "unknown" option. reaction observations conclusions ΔΗ is (pick one) A This reaction is faster above 103. °C than below. AS is (pick one) ΔΗ is (pick one) B This reaction is spontaneous only above -9. °C. AS is (pick one) ΔΗ is (pick one) C The reverse of this reaction is always spontaneous. AS is (pick one) 18 Ar
