Diffusion-system-of-concentration-
扩散系统之浓度分布的装置。管中储放静止液体B，高度为L=10 ㎝，放置于充满A 气体的
环境中。假设与B 液体接触面之浓度为3
C 0 0.01mol m A = ，且此浓度不随时间改变
而改变，即在操作时间内( h = 10天)维持定值。气体A 在液体B 中之扩散系数为
D m s AB
= 2×10− 9 2 。试决定以下两种情况下，气体A溶于液体B中之流通量(flux)。
(a) A 与B 不发生反应；
(b) A 与B 发生以下之反应
A+ B→C ， A A − r = kC
其反应速率常数k = 2×10− 7 s− 1。
(Diffusion system of concentration reference device shown in Figure 3. Tube in the store still liquid B, L = 10 cm height, placed in full A gas environment. Assuming the contact surface of the liquid with the B concentration of 3 C 0 0.01mol m A =, and this concentration does not change with time and change, that is, the operating time (h = 10 days) to maintain constant. Gas A in liquid B, the diffusion coefficient D ms AB = 2 × 10-9 2. Decided the following two test cases, the gas dissolved in liquid B in the A liquid (flux). (A) A and B do not react (b) A and B of the following reaction occurs A+ B → C, AA- r = kC, the reaction rate constant k = 2 × 10-7 s-1.)
