For the reaction $2\mathrm{HI}\left(\mathrm{g}\right)\rightleftharpoons {\mathrm{H}}_2\left(\mathrm{g}\right)+{\mathrm{I}}_2\left(\mathrm{g}\right)$, which one of the following relations between $K_p$ and $K_c$ is true?

$K_p=K_c(RT{)}^{\mathrm{\Delta }{\nu }_{\mathrm{g}};}\mathrm{\Delta }{\nu }_{\mathrm{g}}=0\Rightarrow K_p=K_c$

The equilibrium constant, abbreviated as k, is a quantity that aids in describing the correlation between the quantity of reactants and products present at equilibrium for a reversible chemical reaction at a specific temperature.
