I think making sure that a reader will see the approximate nature of what you have written is important. The numbers at the end are just too tempting if taken at face value. Other than that, I think your answer is still fine; especially the part with the "hundred year" half-life. | |

| Jul 8, 2021 at 6:03 | comment | added | M.L | @Martin-マーチン Yes, I forgot to take that into account. I'm not an expert in this area but what do you think I could say to fix my answer? Should I say that we assume delta G is independent of temperature? | |

Anything > 100 kJ/mol and STP needs a bit more persuasion. As for DFT, without calibration, up to 80 kJ/mol gives you a guesstimate but nothing more. | |

Added some information and calculations while fixing some typos.
