I have a couple of pet theories for “why physics not chemistry” on arXiv use.
(1) arXiv’s structure really wants you to be using latex to produce your paper. My experience is that latex has conquered physics, but not other fields as much. This is supported by my impression that the more theoretical the physics the more computational it tends to be, and the more likely the author is to use latex and arXiv.
(2) The American Physical Society Journals are formatted in quite a minimalist manner, which tries to look quite formal. A typical arXiv preprint using a standard latex template will look like a less clean version of an APS paper. This means that too physicists (who read a lot of APS papers) a journal published paper doesn’t look drastically different to an arXiv preprint. If the popular journals for chemistry and biology format papers to look like Science or Nature articles then they will (at a glance) look quite distinct from a typical arXiv preprint. I think the “does it look drastically unlike a paper at first glance” test will have a very strong bearing on the seriousness people attach to arXiv.
