How do I find the rate constant in this situation?
Say I have two kinds of molecules $A$ and $B$.
The molecules of type $B$ are small and bind onto molecules of type $A$.
(Any number of them may do so, but in practice this number is $\leq 8$.)
We say a molecule of type $A$ is of type $A'$ if it has…

Strip away a small amount of aluminium with household chemicals
I'm trying to turn a 6″ diameter mirror (I have spares) into a two-way mirror. It shouldn't be too hard to remove the backing, but then I need to remove most, but not all of the Aluminium plating.
My current plan is to remove the backing with…

Relationship between Productivity and Yield
I am trying to formulate an optimization problem. Can you help me understand the definition of productivity and yield? Why is there a trade-off between them during the reaction?
Thanks in advance.

CSTR reaction cooling jacket - Transfer Functions
I have a CSTR where an irreversible exothermic liquid reaction takes place. Coolant is flowing in the jacket of the tank to regulate the temperature of the fluid in the reactor and control in this way the concentration of component A. The cooling…

How to stop a lye + oil + water reaction in aluminium container?
I was making soap using a guide for the first time. I accidentally used an aluminium container. It has lye and olive oil in it and was kept on the stove; now it is bubbling and not ceasing (I've turned off the gas).
What should I do to stop it?

Return time after perturbation in a chemostat
I'm wondering how I can derive the return time of the culture cell concentration back to a steady-state in a chemostat after a small perturbation of the bulk culture cell concentration.
More specific, I have the following situation. I have a very…

Efficiency of Gas Liquid Reactions Using Different Methods
I am looking to react MEA (monoethanolamine) with $\ce{CO_2}$. I was planning on doing this reaction by bubbling atmospheric air through water by using an air pump. I have researched that a smaller bubble size will lead to increased efficiency, but…

Pure MEA vs Aqueous MEA Solution for CO2 Scrubbing
I was wondering if using pure MEA (Monoethanolamine) or a MEA solution using water would be a better solution for scrubbing $\ce{CO_2}$.
Based on this image, I would think the key reaction would be able to occur with both pure MEA and an MEA…

How to measure the speed in a catalized reaction?
What is cheaper?
Set up a constant time of reaction and measure the concentration of the products or;
Set up a constant quantity of reactants and, with an indicator, measure the time until the reaction stops.
If you know another protocol, Can…
