Summary

This podcast discusses chemical kinetics and solubility. It begins with an exploration of kinetics, including the general concept, collision theory, rate laws, and the Arrhenius equation. Next, it delves into solubility, covering the general concept, solubility product (Ksp), the common ion effect, selective precipitation, and Henry’s law.

Welcome to MCAT Basics, your ultimate guide to the essential topics you need to master for the MCAT,

0:07.0

brought to you by the physicians at med school coach. Every week, Sam Smith breaks down high-yield MCAT topics, ensuring you're primed for success on test day.

0:16.0

Join Sam as we explore the most crucial subjects outlined by the AAMC, pulled from official practice materials and third-party resources.

0:24.7

Get ready to elevate your MCAT game with topics tailored to maximize your score potential.

0:29.9

Hello, I'm Sam Smith.

0:32.5

This podcast is going to cover kinetics and solubility.

0:36.2

In terms of kinetics, I will cover the general concept of

0:39.5

chemical kinetics. I'll talk about rate laws, and that's where I'll spend most of the time in the

0:44.5

kinetic section of the podcast is on rate laws. And then I'll get into a little bit on the variables

0:49.8

that affect kinetics of a reaction, things like temperature and pressure, different types of solvents,

0:55.1

stuff like that. And then I'll get into solubility, again, starting with the general concept of

0:59.3

solubility, and then I'll get into solubility constant, or a cusp or kSP. And then I'll talk about

1:05.5

the common ion effect, and lastly I'll talk a bit about selective precipitation. And this material is going to show up on one out of the four MCAT sections.

1:14.6

That is going to be the Chemphiz section.

1:16.6

Obviously, this is Gen Chem stuff, so you're mostly seed in that section.

1:21.6

This stuff is fairly important.

1:22.6

I'd put it somewhere along the lines of like 7 out of ten on the yield score if 10 out of 10 was

1:28.7

the yield for like amino acids or something that comes up 10 different times on the mcat so this

1:34.7

is stuff that you'll definitely see it might not be 10 questions but you'll definitely get a few

1:39.4

questions on kinetics and solubility and you're most likely to see some kind of calculations.

1:44.8

These are typically pretty simple calculations.

1:46.7

You just need to be able to remember the equations
