Answer
$K_{c}$ is a mathematical expression for calculating the equilibrium constant using concentrations of products and reactants.
$K_{p}$ is a mathematical expression for calculating the equilibrium constant using partial pressures of products and reactants. It is applicable on systems in gas phase.
The relationship between $K_{c}$ and $K_{p}$ is:
$K_{p} = K_{c}(RT)^{\Delta n }$ where $R = 0.0821 \frac{L.atm}{mol.K}$
