【Abstract】 Equilibrium costant of the reaction of CO deoxidizing zinc oxide and generating gaseous zinc and CO 2 was measured in new method at many temperatures. The equation Lg K p =-10?630/ T +6.92 was obtained and the calculated result was compared with that of the equations in many documents. At 1 250 K, the smallest K p of the equations in many documents is 0.012?4 and 0.013 6 below that of this study, the largest K p is 0.032?6 and 0.006?4 greater than that of this study, the others are close to that of this study. The differences between the others and this study are smaler than 0.005, it is thus proved that the result of this study is reliable. [更多还原
