In this video we go over how to calculate activation energy using the Arrhenius equation. That formula is really useful and versatile because you can use it to calculate activation energy or a temperature or a k value.
I like to remember activation energy (the minimum energy required to initiate a reaction) by thinking of my reactant as a homework assignment I haven't started yet and my desired product as the finished assignment. The activation energy in that case could be the minimum amount of coffee I need to drink (activation energy) in order for me to have enough energy to complete my assignment (a finished "product").
As with all equations in general chemistry, I think its always well worth your time to practice solving for each variable in the equation even if you don't expect to ever need to do it on a quiz or test. I can't count how many times I've heard of students getting problems on exams that ask them to solve for a different variable than they were ever asked to solve for in class or on homework assignments using an equation that they were given. That is a classic way professors challenge students (perhaps especially so with equations which include more complex functions such as natural logs adjacent to unknown variables).
Hope this helps someone! Let me know down below if:
- you have an easier way to do these
- you found a mistake or want clarification on something
- you found this helpful :D
* I am not an expert in this topic. I am just a clinical lab scientist and life-long student who learns best from videos/visual representations and demonstration and have often turned to Youtube for help learning. My hope is that others in the same boat find and benefit from this.
