I am officially changing the post to a tag-blacklist-request.
I think, and so far there was no objection, that it is a meta-tag, and that it is not helpful. Unlike homework or reference-request it basically only serves as a placeholder. I would say it is on par (maybe a tiny bit better) with chemistry, which has been blacklisted for quite some time.
- What does blacklisting mean?
First, it means the tag will be mass-removed from all questions. This is preferable to removing it in a mass retagging from about 900(+) question while flooding the homepage. Second, it will be banned from being reapplied. - Why blacklist?
I believe the tag will reappear, and once it is there it will again spread uncontrollably. When the tag cannot be reentered again, we don't have to worry about it. If it would have been applied to only a few questions, I would not bother to involve the developers, but it is on almost 5% of the questions. - What needs to happen?
- $\color{green}{\textbf{(Done)}}$ We need to clean up the cases where reaction is the sole tag. That means manual retagging, editing, etc. This is necessary either way. After the delete all those questions would be untagged. We should avoid that. I am monitoring if this tag appears, it can due to migration, but it is better to have precautions in place.
If you want to help out, you can use this SEDE query to find questions, which only have this tag. - $\color{green}{\textbf{(Done)}}$ Wait for this post to gain enough votes to consider it a consensus. (I'd say we should see a double digit with at least a two in front.)
- $\color{green}{\textbf{(Done)}}$ Once consensus is reached, we need to contact the developers and let them go about their business. They will help us to silently remove the remaining uses of the tag ("burnination") and also prevent future uses of the tag ("blacklisting").

If you agree with the proposal, please upvote Klaus' answer. (You may upvote the question, but the answer is more important.)
If you disagree, please leave a new answer outlining why. If there is already an answer disagreeing with the proposal, please vote on it instead.
As usual we will disregard any down-votes to exclude double counting.
If you think there is something left unsaid, you can of course always comment or add another answer.
We've all seen it, we've probably all applied it at least once: reaction.
Yes, sometimes desperate times need desperate measures, and I admit I have used this one. And if I recall correctly, I even wrote the description:
This general tag should be used if the question is about a specific (set of) reaction(s). It should be specified with other tags like stoichiometry, inorganic-chemistry, organic-chemistry, acid-base, ... .
For what it's worth, I (now) think it is an empty tag, with no value whatsoever. Maybe one of the most worthless meta-tags there is. On par with chemistry. It has incredible 930 (!!!) uses, of which there are 54 questions where it is the only tag.
Recently I have seen it used as a placeholder from new users, because you have to specify a tag. Well, that specific one kind of hurtz™ my eyes and mind. What shall be done?
If you consider leaving a comment, consider leaving an answer instead so that others can vote on it and we reach a conclusion faster.
