Rates of reaction, Taught not just answered.
A real-time, 1:1 lesson on Rates of reaction: an AI teacher explains it out loud while it visualizes every step. Interrupt it, ask why, and it checks you got it, in 26 languages.
The idea
What is Rates of reaction?
Rates of reaction describe how fast reactants turn into products and what controls that speed. Collision theory says particles must collide with enough energy, the activation energy, and in the right orientation, so higher concentration, higher temperature, greater surface area and catalysts all speed things up by increasing effective collisions. Experimentally, the rate law expresses rate as a constant times reactant concentrations raised to their orders, which must be found by experiment rather than from the balanced equation. Half-life is constant for first-order reactions.
Where it appears: Class 12 CBSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET.
Where learners get stuck
Why Rates of reaction is hard
Learners assume the reaction orders equal the stoichiometric coefficients, and they think temperature speeds reactions only by increasing collision frequency when the far bigger effect is the fraction of collisions above the activation energy.
The picture a good explanation starts with: A reaction energy profile with reactants, a hump labelled activation energy and products below, plus a second dashed lower hump showing the catalysed path.
A lesson, step by step
How a lesson on Rates of reaction goes
01
Ask
Type or say "Why does a catalyst speed up a reaction without being used up?" in your own words, in any of 26 languages.
02
Plan
The tutor plans a storyboard, one picture per idea, starting with a reaction energy profile with reactants, a hump labelled activation energy and products below, plus a second dashed lower hump showing the catalysed path.
03
Explain
It explains Rates of reaction out loud while the picture builds step by step, pitched to your level (Class 12 CBSE and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
05
Check
A checkpoint question makes sure the idea landed, and Tests keep the practice going.
06
Your notes
Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.
Ask it anything
Questions learners ask about Rates of reaction
- Why does a catalyst speed up a reaction without being used up?
- How do I find the order of a reaction from data?
- Why does a small temperature rise speed a reaction so much?
Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.
Questions
Asked, Answered
Can LetMeTeach explain Rates of reaction?
Yes. Ask in your own words and the tutor plans a lesson on Rates of reaction: it starts with a reaction energy profile with reactants, a hump labelled activation energy and products below, plus a second dashed lower hump showing the catalysed path. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.
Where does Rates of reaction come up?
Class 12 CBSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.
Can I learn Rates of reaction in my own language?
Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
