It has been demonstrated in this experiment that the reaction rate and the sulfur activity, as determined by kinetic methods, are only a function of temperature or sulfur concentration when the flow rate of the input hydrogen is maintained at 200 or 300 ml / min, whereas Cu-S The melting point of the reaction rate of hydrogen and the turning point, it is just the transition point of Cu-S system .4 sulfur and copper activity given by the following equation u_S = (d (S%)) / (dt) = kα_Sp_ (H_2) ~ (1/2) Among them p H 2 = 1 atm. The stoichiometric composition of the sulfur content in CuS is chosen to be the standard one and α S = 1, so the copper activity is calculated from the Gibbs-Duhem equation: α Cu = - N_S / 1-N_S) integral from n = 0.5 to (0.5-x) (dlgα_S)
