※ 引述《chetsai (Ivan)》之铭言：
: A rapid,first-order liquid reaction is carried out in a
: fixed-volume,well-mixed flow reactor under isothermal condition.Let τ and Ts
: be the space time and the time necessary to reach 99% ofthe steady-state
: concentration,
: respectively.Please derive the following relation: Ts=4.6/k,where k is the
: specific reaction rate.
: 我有疑问的是这题到底是steady state 还是 unsteady state 呢???
: 而且到底是batch 还是flow system呢?
: 因为我的想法是: flow 系统他得体积是固定的 ,且浓度是随space time变
: batch 系统浓度是随时间变的
: 所以有点被搞混!! 想请问我观念哪里错了??
那可以教我一下用UNSTEADY-STATE怎麽算嘛???拜托!!!
