Spectrophotometry and Beer's Law
We've learned about kinetics already, but how do we gather kinetic data? One clever method is by analyzing how the color of a solution changes over time, which is an indication of the concentration of certain compounds that interact with...

Le Chatelier's Principle: Part 2
What exactly is Le Chatelier's Principle? And why is it important to learn it to understand chemical reactions?

Limiting Regents and Percent Yield
Chemistry doesn't always work perfectly, silly. Molecules are left over when one thing runs out! Also we never get all of the products that we thought we might by doing the math. You gotta know about the limiting reagents and the percent...

Practice Problem: Ozonolysis Reactions
Ozone isn't just for shielding us from harmful UV radiation! It's a handy-dandy synthetic tool. Try these on for size.

Factors Affecting the Rate of Reaction
The video discusses the factors that affect the rate of chemical reactions. The first factor is the number of collisions with enough energy to react. Other factors include changing the pressure, concentration, surface area, and...

Practice Problem: Hess's Law
If we want to find out some information regarding the enthalpy change of a reaction, but we don't want to perform the reaction, we can use Hess's law, which allows us to manipulate thermochemical data for related reactions. Let's...

Practice Problem: ICE Box Calculations
Sometimes when we do equilibrium calculations, we have to use an ICE box. Don't worry it won't be chilly, it stands for initial, change, and equilibrium. Let's use this technique to calculate some equilibrium concentrations!
Professor Dave Explains
Practice Problem: Solubility Product Constant Calculations
We've learned that there are ionic solids that are insoluble in water, and while for the most part that's accurate, we are bending the truth a little bit. Even compounds that are totally water insoluble will still dissolve a teeny tiny...

Writing Chemical Equations in Words
Sometimes we want to talk about chemistry without using fancy symbols, just with words. Shouldn't we be able to do that? Yes, we should! Here's how.

Understanding Mass Changes in Chemical Reactions
This video discusses mass changes in chemical reactions. The Law of Conservation of Mass is introduced, which states that atoms are not lost or gained during a chemical reaction. Two examples are given: the reaction of sodium with water...

Organometallic Reactions Part 3: Reductive Elimination
Reductive elimination is essentially the opposite of oxidative addition and the products of one process can be the reactants of the other process. What conditions are most favorable to reductive elimination?

Calculating and Measuring Chemical Reaction Rates
The video discusses the concept of the rate of a chemical reaction and how it can be calculated and expressed in various ways. The examples used in the video include measuring the amount of product formed or reactant used up over a...

Chemical Equations
Chemical equation shows the overall chemical change of reactants into products. It's a bit like a detailed cooking recipe, but where all the ingredients and all the products are written down, even the ones you can't necessarily see. The...

Integrated Rate Equations
It explains zero order reaction and derives its rate constant. It describes the first order reaction rate constant. It discusses about half-life of a reaction.

Kinetics: Initial Rates and Integrated Rate Laws
Who likes math! Oh, you don't? Maybe skip this one. Unless you have to answer this stuff for class. Then yeah, watch this.

Le Chatelier's Principle
If a system is at equilibrium, and we do something to it, it will shift in a particular way. It is quite easy to predict the behavior of equilibria if we know about these three simple situations!
Professor Dave Explains
Chemical Equilibria and Reaction Quotients
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium. And we need to be able to predict how much stuff there will be at equilibrium! Get ready to...
