Could someone explain in lamens terms the difference between Q and K...Qp and Qc....Kp and Kc....and throw in the Kp' (prime?) how do you find constants, and how come my notes say Q and K are the same, but clearly are not.

The equations for Q and K are the same, but the conditions are different. Use Q when the system is not at equilibrium (or if you're not sure it it). If Q is different from K, the system is not at equilibrium. Use K for a system at equilibrium.

Basically, equilibrium constants in gases are given as Kp, since you measure pressure. In solution, the constants are Kc, since you measure concentrations. I don't know about the Q, unless Q stands for a "generic" quantity, which these K's are related to.

Q is used in thermal constants
Qp-----heat at constant pressure
Qc-----heat at constant volume
