    I was wondering if 1,3-Cyclohexadiene would spontaneously decompose into the more stable benzene + hydrogen gas. Would it?

    Oops, sorry about that. I'm too used to assuming STP.

    273 K and 1 atm.

    It doesn't, no.

    To answer the question more generally, the reason why things don't spontaneously combust is that you've got an transition-state barrier. You need an 'activation energy' for the reaction to happen.

    Aldrich sells 1,3-cyclohexadiene for $45.60 per 5 mL, $534.00 for the economy-sized 100 mL vial...

    Ah, I see.

    Thank you for expanding my homegrown knowledge of organic chemistry.
