Provide a clear and concise overview of the new feature requested.

This is a documentation item raised by @beckyalexander in #1991:

I'd like to re-open this. At IGC11 I've learned that I'm not the only one who got unrealistic results with the RxnRates diagnostic. @viral211 suggested that it might be because this diagnostic is written out before the chemistry solver. Perhaps there should be a warning on the website that states that this diagnostic is not yet working so that people do not do long simulations expecting it to work. Currently the alternative is to tag reactions in KPP and turn on the Prod/Loss diagnostic.
