8. Suppose that the enthalpy change of the dissociation of double-stranded DNA base pairs is ~ of base pairs and the corresponding entropy change is 30. At what temperature (℃) can you expect a double-stranded DNA to dissociate spontaneously? (10%)

2. If we consider a 850 MHz NMR spectrometer, the resonance of 1H nuclear is 850MHz. calculate the energy that is required to make the transition from the lower energy state to the higher state. Meanwhile, please explain how to calculate the population ratio of molecules in the higher and lower states? (8%)
