The reduction rate determined by this study is of an apparent first order reaction of overall wt-% of FeO. The measured apparent activation energy is 222.60 kJ/mol. The empirical equation of the rate is v=-(W_s/A)dc/dt=1453.0[exp(222600/RT)]·C Experimental results show that the convection diffusion is the rate-controlling step in the reduction of molten FeO by solid carbon.
