Textbook Question

Chapter 9, Problem 47P

The 1 H NMR study of DMF (N, N-dimethylformamide) results in different spectra according to the temperature of the sample. At room temperature, two signals are observed for the protons of the two methyl groups. On the other hand, at elevated temperatures (> 130 °C a singlet is observed that integrates for six hydrogens. Explain these differences.

Chloroform, long used as an anesthetic and now considered carcinogenic, has a heat of vaporization of 31.4 kJ/mol. During vaporization, its entropy increases by 94.2 J/mol.K. Therefore, select the alternative that indicates the temperature, in degrees Celsius, at which chloroform begins to boil under a pressure of 1 atm. A) 28 B) 40 C) 52 D) 60 E) 72

If we assume a system with an anodic overpotential, the variation of n as a function of current density: 1. at low fields is linear 2. at higher fields, it follows Tafel's law Obtain the range of current densities for which the overpotential has the same value when calculated for 1 and 2 cases (maximum relative difference of 5% compared to the behavior for higher fields). To which overpotential range does this correspond? Data: i = 1.5 mA cm², T = 300°C, B = 0.64, R = 8.314 J K1 mol-1 and F = 96485 C mol-1.
