I think brackets are usually used to denote concentration, such as [J] is the concentration of solution/gas J, whereas parentheses are used to show that you are multiplying values. In the ideal gas law, Dr. Lavelle used brackets when rewriting the formula as P = [conc.]RT, but for calculations it shouldn't matter.
I'm pretty sure brackets indicate concentration so for Kc [H20] indicates the concentration of water, but with Kp you have (PCl2). You don't need brackets to indicate concentration for this because the P indicates the pressure of the gas. I hope this helps!
My T.A. said that brackets indicate concentrations while parentheses are for calculating the K of partial pressure. It would be incorrect to do [Pco2] for example because you'd be trying to calculate the concentration of a partial pressure, which isn't correct.
