Abstract
In this report, the theoretical consideration of phenomena of cylindrical diffusion with rapid reaction is undertaken. The relations between time and position of boundary line caused by rapid reaction, concentration distribution, and amount of diffusing substance are derived. Also, experimental formulas are set up, and their relations to the theory are investigated.
The theoretical and experimental formulas are applied to the experimental results (the previous report) on the formation of Zn-xanthate, and quantitative analysis is undertaken. From the examination at various temperatures, it is concluded that activation energy for the diffusion of ZnSO4 with Zn-xanthate formation is 3.5kcal/mol., which is about 60% of activation energy for ZnSO4 under normal diffusion.
