K to Kc equation

Postby Chew 2H » Wed Feb 07, 2018 5:42 pm

In the equation that converts K to Kc, what does the "c" represent?

Kc is the equilibrium constant in terms of molar concentrations. See section 11.6 in the textbook.

K usually refers to the equilibrium constant at equilibrium pressures, while Kc is the equilibrium calculated using the equilibrium concentrations. I believe that gases are usually given in partial pressures though.
