Why can we use stoichiometric coefficients in the equilibrium-constant expression? [duplicate]
I just studied the chapter on chemical kinetics on Coursera, wherein I was repeatedly admonished not to use the stoichiometric coefficients in the rate law formula. I was told that this formula has to ...

Chemical equilibrium — why multiplication, rather than addition? [duplicate]
Why do we multiply (and not take the sum) the concentration of products and reactants when more than one entity is present in either side and rise the power to the coefficient term?
Suppose either
$$...

Chaos in chemical reactions
I recently read about Chaos Theory and was wondering if a chemical reaction results in or shows characteristics of chaos (I found a few examples of such reactions here)
Chaos theory concerns ...

Intuition for why catalyst affects both forward and reverse reactions equally?
I have looked for quite a long time on the site however all the answers involve mathematical explanations involving Arrhenius's equation. I would really like an intuitive reason (or one using ...

Can a zeroth order reaction be reversible?
After recently studying about chemical equilibrium, I was convinced that the forward and backward reaction rates meet each other at equilibrium.
However thinking about zeroth order reaction annoyed ...

kinetic reaction rate greater than extent of reaction for equilibrium
I'm comparing a model with chemistry at equilibrium versus a kinetic one.
I take a network of two reactions: methane steam reforming (MSR) and water gas shift (WGS) at 700°C.
I calculated extent of ...

Can a multi-species system oscillate around equilibrium?
In reading about chemical oscillations such as those that occur in the Belousov–Zhabotinsky reaction (BZ), it's often reported that these reactions were initially not taken seriously, because of a ...
