Here I look at 3 examples of how the rate equation can be obtained from experimental runs. The order of the reaction for each of the reactants is determined, allowing the rate equation to be constructed. In the third example I rearrange the rate equation to make the rate constant (k) the subject of the equation. I then work out its value and units. In the next video "Kinetics 2" I look at 3 further examples, which are a little more difficult.

Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.

This video explains how to calculate economic order quantity using the time-tested Wilson EOQ formula.
The video provides a step-by-step process to defining the economic order quantity for any company. It takes into consideration the company's annual or yearly consumption, the price it pays for each unit it purchases for its inventory, the cost to make that purchase and finally, the company's costs to hold inventory on a monthly basis.
Determining the annual or yearly consumption is fairly straightforward. Simply take a total of all the inventory of a given part used in a year. Next, take the amount your company pays for that part or raw material.
Determining your company's costs to purchase doesn't merely involve totaling your total volume multiplied by price. Instead, it's more about defining what it costs your company to make a purchase. How much does it cost your company to purchase from a vendor?
Your costs to purchase include time spent to approve and sign purchase requisitions. It also includes the time spent placing that order and sending it to your vendor. Next, the costs of inspecting the order are accounted for and finally, the costs of paying your vendor.
The Wilson EOQ formula involves doubling your yearly consumption total and multiplying it by your company's cost to purchase. This amount is then divided by the sum of the raw material or part's price multiplied by its inventory holding costs.
The Wilson EOQ formula is an excellent tool for making sure your company doesn't buy too much or too little.

065 - The Equilibrium Constant
In this video Paul Andersen defines the equilibrium constant (K) and explains how it can be calculated in various reversible reactions. The equilibrium constant is a ratio of the concentration of the products to the concentration of the reactants. If the K value is less than one the reaction will move to the left and if the K value is greater than one the reaction will move to the right.

Pre-Algebra on Khan Academy: No way, this isn't your run of the mill arithmetic. This is Pre-algebra. You're about to play with the professionals. Think of pre-algebra as a runway. You're the airplane and algebra is your sunny vacation destination. Without the runway you're not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We're about to take off!

This lesson is taught by Arvind Arora who is a passionate educator of Chemistry. He loves to teach Chemistry for IIT JEE aspirants. His lesson video has benefitted a lot of IIT JEE aspirants for both JEE Mains and JEE Advanced.
Chemical kinetics, also known as reaction kinetics, is the study of rates of chemical processes. Chemical kinetics includes investigations of how different experimental conditions can influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that can describe the characteristics of a chemical reaction.
