## What do you learn in Chemical Kinetics

Chemical Kinetics covers the rates and mechanisms of chemical reactions. You'll explore factors affecting reaction speeds, rate laws, reaction order, and activation energy. The course dives into collision theory, transition state theory, and catalysis. You'll also learn about complex reactions, chain reactions, and how to determine reaction mechanisms from experimental data.

## Is Chemical Kinetics hard?

Chemical Kinetics can be challenging, but it's not impossible. The math can get a bit tricky with differential equations and complex rate laws. Some students find the abstract concepts hard to grasp at first. But once you get the hang of it, it's pretty cool to see how reactions actually happen on a molecular level. Practice problems are key to mastering this course.
