I just realised that the half-life equation (t1/2 = 1/k[A]0) for 2nd order kinetics doesn't work for all durations (t).

5:16 AM

I realised this as I was doing a problem which required me to calculate the concentration of a particular reactant involved in a 2nd order reaction after a particular duration, which was much longer than the half-life

Why do people love subscripts so much?

@Martin-マーチン What is the meaning of life?

@orthocresol yeah, and he noticed it like after all the people in SE

Martin - マーチン

@M.A.R. dying

M.A.R.

@Martin-マーチン With the same logic, the purpose of subscripts is for you to edit them

Martin - マーチン

hmm... i would have expected more

M.A.R.

@Martin-マーチン More from?

Martin - マーチン

i don't know... I just find it very irritating why there have to be cascades of sub/superscripts...

@Martin-マーチン You just have to accept life is generally irritating

Exponents (150) $x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x^{x...

subsup is like flies that always appear when you're enjoying food somewhere green

Martin - マーチン

@M.A.R. no it isn't

M.A.R.

@Martin-マーチン OK. Life is generally irritating when you're not drunk

Martin - マーチン

no it isn't

M.A.R.

9:57 AM

@Martin-マーチン so what is it then?

Martin - マーチン

dunno, but i wouldn't say it's irritating

M.A.R.

well it's not dunno

Dunno, maybe

It does sometimes get more dunno than usual

Martin - マーチン

sometimes I really wonder if you're doing drugs...

what you say makes no sense... but I guess that is the intention...

you're trying to confuse me.

M.A.R.

@Martin-マーチン . . . I am

But drugs drugs, not crystal drugs

Such as Sevelamer hydrochloride

Martin - マーチン

well, all the chemistry, none the fun

Kinda fun watching blood P level decreasing though

Martin - マーチン

okay... if you say so...

Why are some people constantly writing $\mathrm{SN_2}$ instead of $\mathrm{S_N2}$ is it taught differently in other parts of the world?

A: Can isonitriles be used to make primary amines?

My textbook has an easy way. Since the NC bond is highly polar, you can simply hydrolyze the given $\ce{R-NC}$ molecule. The electropositive $\ce{H^+}$ will attach to the more electronegative $\ce{N}$ atom, while the $\ce{OH^-}$ will attach to carbon atom. This will use two molecules of $\ce{H2O}...
