The reduction of ferrous chloride with hydrogen at atmospheric pressure has been investigated at temperatures up to 583°C. The results show that the reaction rate is limited by the rate of diffusion of hydrogen chloride produced in the reaction. At constant temperature the rate is proportional to the difference between the equilibrium partial pressure and the back pressure of hydrogen chloride. The reaction rate has a strong dependence on temperature, corresponding to an “apparent activation energy” of 19.9 K. cal./mole. A reaction mechanism involving vaporization of ferrous chloride is suggested.
