- 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) 72arrow_forwardIf 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.arrow_forwardAnswer by equation pleasearrow_forward
