Re: Kp and Kc
Kc and Kp are both equilibrium constants used for gas-phase mixtures. However while Kc uses molar concentration of the gases, Kp uses partial pressure of the gases involved.
Re: Kp and Kc
While this is not a difference, also keep in mind that you calculate both of them the same way, with the products on the top and the reactants on the bottom!

Re: Kp and Kc
The former is referring to the partial pressures and the latter is referring to molarity. You use the former with gases and the latter with gases and aqueous solutions.

Re: Kp and Kc
Is it possible to use Kc when only gases are involved in the reaction? If so, how do you know when to use Kp and when to use Kc?

Re: Kp and Kc
Kc uses molar concentrations while Kp uses the partial pressures of gasses inside the closed system

Re: Kp and Kc
I think it just depends on the facts you are given in the problem. When you are given concentrations of gases, you are using Kc, while if you are given the partial pressures, then you should use Kp.
