If in a batch reactor both aeration and agitation is provided, but due to change in agitation there is not significant increase in product yield, but due to aeration and sparging there is significant increase in product yield? so how to determine which type of reaction it is?means the reaction is dependent on what?
What is the role of both of them in the reaction and how to choose which is important in your reaction (Mass transfer or kinetics or both) and how should we determine the same?
Probably, you are asking about the the rate of mass transfer of O2 from the gas to liquid phase. This rate is strongly dependent on the ratio of solution volume to the surface area of the liquid phase. Design your experiment to make this ratio as low as possible. The rate of O2 mass transfer usually becomes important if the rate of product formation is > 10^-3 M/s
@Geleti Thank you for explaining how the term 10 ^-3 M/s is defined. Is it generic or case specific. I mean its applicable for all product/product formation?
The best would be the dioxygen consumption rate. It's also OK for the main product. Just estimate the rate of your reaction and see where you are.
