Is Keq different from Kc, or does it represent the same thing? Also, will we be marked wrong if we wrote Keq instead of Kc for the chemical equilibrium equation?

I believe that both Keq and Kc are used to represent the equilibrium constant. I don't think you would be marked down for using one over the other because Professor Lavelle mentioned in lecture that K, Kc, and Kp are often used interchangeably to represent the same thing, the equilibrium constant.

Keq is used to represent either Kc or Kp, but I don't think you will be marked down if you use Keq all of the time. However, just to be safe I would use Kc when dealing with molarity and Kp when using partial pressure.

Kc should be used when talking about concentrations and it is just under the umbrella of Keq which could be either Kp or Kc.
