It’s used in TMS devices, which is a treament that I’m seeking for my depression. Unfortunately, the waiting time for me to get that treatment is over 6 months. If only I had the mental energy to make my own machine…

So I’ve been running with the magnet thing for my proof. Theoretically, if I were to put three magnets together, placing them in a way that makes the middle one spin incredibly fast, could I make a radio wave strong enough for long distance communication?

If you’ll make electromagnetic waves with it, then maybe. But you would need some operating machine if you would want to send something else than constant signal.

the equation for determining the enthalpy change from turning a set of reactants into a set of products is just the formation enthalpy of the products - the formation enthalpy of the reactants, right?

Indeed. It will be negative if products < reactants or positive if products > reactants.
I presume the dash you put in the second term is supposed to be a minus, right?

I was wondering what about reactions that include catalysts

2 Likes

To my knowledge catalysts only “improve” the intermediate process between the states of reactants and products, meaning they shouldn’t influence this.

there are also reactions that basically require a catalyst to occur, like most reactions catalysed by proteins
and enzymes are all catalysts, as part of how an enzyme is determined is whether or not it catalyses a reaction

I wonder if life could exist which wouldn’t use catalysts…

only if you count a self replicating 3d printer that can make the materials it needs to replicate from stuff it can gather
and such a 3d printer would also be able to print mining drones

Would nanobots (like the grey goo thing) count as a lifeform if they were real?

yes, but they would have to use catalysts, and basically just be extremely condensed cells that have a capsid instead of a membrane or cell wall
if they’re actually nanobots and not microbots, at least

So if a robot can replicate reliably, it counts as a “lifeform”?

I wonder how this would look like if you included uncompetitive and noncompetitive (yes, they are different) inhibitions?

I haven’t heard of these quite yet… Do you perhaps know how it would go with them present?

It is has been a while since I have taken biochemistry. Oh. I found a free text online that explains enzyme inhibition.

Since these all seems to be enzymes I’d presume they follow what we have already established about enzymes here - they modify the pathway, but not the reactants or the products themselves.

I meant in the aspect of lowering the energy barrier required for reaction to occur; formation entropy of product doesn’t change (?), nor entropy of substrates

So still we reach the same conclusion as before…
