How it works
Explore **A → B** kinetics with a simple rate law. Turn on **Arrhenius** to see how **temperature** and **activation energy** change the rate constant **k**. A **catalyst** lowers the effective barrier (modeled here as a multiplier on **k**). Curves use **closed-form** solutions for 0th / 1st / 2nd order in **[A]**.
