K'

Postby Bijan Mehdizadeh 1B » Tue Jan 08, 2019 10:03 am

Why do we write K' when referring to K values that have fraction mole ratios? Is K' really the derivative of K in this case?

I think k' refers to the inverse of k, meaning if we know k of a forward reaction, the reverse reaction equals k' or 1/k.

As said above, K' usually is written to refer to the equilibrium constant of the reverse reaction whereas K represents the equilibrium constant of the forward reaction. You don't have to take any derivatives, it is just a way of notation.

K' refers to the reverse reaction. You can find K' by calculating 1/K.
