Rather
$$\ce{2 NaOH(aq) + CO2(g) -> Na2CO3 (aq) + H2O}$$
and analogically on the solid $\ce{NaOH}$.
Bicarbonate in aqueous solutions cannot survive the excess of hydroxide, forming carbonate.
$$\ce{HCO3^{-}\ (aq) + OH- (aq)<=>> CO3^{2-}(aq) + H2O}$$
The same is further enforced by dehydration effect of solid hydroxide.
$$\ce{NaHCO3(s) + ...

I have worked on a computational project where I had to study the sites of deprotonation in this molecule:
When deciding between mechanisms I had to consider both thermodynamic and kinetic. For example, I had this case: deprotonations of two different hydrogens(bond with N Blu atoms in the picture)were similarly thermodynamically favored (similar free Gibbs ...

What I think: A macroscopic chaotic system is a system whose "components" influence each other, and the macroscopic outcome depends on the status of the components. This happens for the two-arms pendulum, for air particles in cigarette smoke, and for particles in wind. Each microscopic variation can be propagated between particles, and the final status of ...

A homogeneous reaction mixture can hardly show macroscopical chaotic behaviour. Well known cyclic counterexamples exist, and practically any reaction which proceeds faster than diffusion or mechanical mixing can homogenise it again (e.g. any reaction that generates a lot of heat!) is liable to show some intermediate chaotic concentration gradients. Its ...

Reactions that are probably not elementary
Whenever there are more than three reactants, it is unlikely that the reaction is elementary. Tenary elementary reactions are already quite rare. If you have a reaction like
$$\ce{2C8H18 + 25 O2 -> 16 CO2 + 18 H2O}$$
it is impossible for 27 particles to come together at once, so you would expect some ...
