This post was last edited by zshiwei2008 on 2015-12-3 at 13:10. Points system for the daily question: Participation – 1~3 points; Correct answer – 5 points; In-depth analysis – 5~10 points. The answer is provided the next day. Due to limited capabilities, I am unable to provide more in-depth explanations for each question; therefore, on the second day, in addition to offering reference options, I will also remove the restriction on reading replies. I hope that all candidates can learn from one another and improve together! Daily Question (2015-12-1): 1. One of the necessary conditions for achieving equilibrium separation in a two-component homogeneous mixture is ( ). A. Distribution coefficient k > 1 B. Distribution coefficient k < 1 C. Separation factor α = 1 D. Separation factor α deviates from 1 2. One of the characteristics of rate separation is that the material being processed and the product are usually ( ). A. In two equilibrium phases B. In the same phase state, with only differences in composition C. Under the influence of an external force field D. On either side of a selective membrane Answer: Question 1: D Question 2: B
D. The separation factor α deviates from 1 D. Located on both sides of the selective membrane
