Kinetic equations represent a way of describing the time evolution of a system consisting of a large number of particles. Due to the high number of dimensions and their intrinsic physical properties, the construction of numerical methods represents a challenge and requires a careful balance between accuracy and computational complexity.

Numerical methods: example too simple

In the new section Numerical methods, the detailed example given is the simple first-order rate law. However this simple example does not require numerical integration software. As explained in most physical chemistry or chemical kinetics textbooks, the answer is a simple exponential function, and it can be evaluated with a hand calculator or an Excel spreadsheet. I would suggest finding an example which cannot be integrated analytically and which actually requires one of the software programs (or apps) listed. Dirac66 (talk) 03:42, 30 January 2021 (UTC)

Original: Stopped flow methods, which can reduce the mixing time to the order of a millisecond[8][9][10] The stopped flow methods have limitation, for example, we need to consider about the time it takes to mix gases or solutions and are not suitable if the half-life is less than about a hundredth of a second.

Explanation: There is a typo. The word 'about' should not be in this sentence. Storsmellen (talk) 14:09, 20 March 2022 (UTC)

Lead Image Implemented

Hi everyone.

Generic reaction coordinate diagram showing the effect of a catalyst on activation energy in an exothermic reaction from reactants X and Y to product Z.

I’ve added a lead image to the article: a generic reaction coordinate diagram showing the effect of a catalyst on activation energy in an exothermic reaction (X + Y → Z).

I chose this diagram because it reflects several of the key ideas mentioned in the lead, including activation energy, catalysis, reaction progress, and the relationship between reactants, transition states, and products.

This diagram is also used in the catalysis article, but not as a lead image, and I think the reuse here is reasonable given how directly it relates to the topic. The only limitation I see is that it is representative and abstract rather than practical or demonstrational.

If anyone has suggestions about the choice of image, caption, or placement, I’m very happy to discuss and adjust as needed.

Poor choice because it also has the difference of single-step vs multi-step and is less accessible because it has a greater reliance on color to distinguish the two paths. Compare with File:Activation energy.svg, which is clearer in both regards (and that also has clearer text definitions of the "Ea"). DMacks (talk) 15:26, 5 January 2026 (UTC)

Hi.

Just implemented the other image into the article.

That other image is definitely better, I like how it's clearly labelled.

Thank you.
