K constant

Postby Tiffany Cao 1D » Sat Nov 25, 2017 5:33 pm

I noticed that K was written out in brackets [X] or in parenthesis with P (Px). What is the differentiation?

The brackets mean that it is the concentration (mol x L-1) or the Kc for the reaction. The parenthesis with the P means that the K is in partial pressure (either barr or atm).

Is there a way to convert from atm to barr, when dealing with partial pressure?

Brackets is for concentration (Kc) whereas the P is for the partial pressure (Kp)

The brackets [Kc] is for calculating equilibrium concentrations (done in M) where (Kp) is for calculation equilibrium pressure (done in atm or barr)

Brackets means that the K is Kc and should be in terms of concentration. P means that K is Kp and should be in terms of partial pressure.
