A certain amount of chlorine gas is in a tank at a pressure of 419.5 mmHg and a temperature of 327 Celsius. Carbon is put into the tank according to c+2Cl2 -> CCl4. At the end of the process, the pressure drops to 316.2 mm Hg, assuming that not all the chlorine has reacted and assuming that the temperature does not change, calculate the partial pressures of the gases in the mixture at the end of the process.
