AI Thread Summary
Life arising from non-life today is considered unlikely due to the complex conditions required for such processes, which are not present in the same way as billions of years ago. The discussion highlights that any organic compounds formed today would likely be quickly broken down without protective mechanisms. Participants debate the assertion that life cannot arise today, with some encouraging a more open inquiry into the possibility rather than dismissing it outright. The conversation emphasizes the need for a deeper understanding of the conditions that foster life's emergence. Overall, the consensus leans towards skepticism about spontaneous life formation in the current environment.

Could life arise from non life today? Why?

I know that it's not possible today but I'm not sure why?

Where?
 
Borek is asking where life could arise--as on Earth or otherwise. If some tasty self-similar replicating organic compounds arose on Earth, they would be easily digested if they didn't come pre-equipped with some protective mechanisms.

HOW do you "know that it's not possible today"? I liked your post better when you were asking if it was possible rather than simply asserting that it is not!

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...
