$H_{2_{(g)}} + Cl_{2_{(g)}} \rightleftharpoons 2HCl_{(g)}$

(C) The relationship between $K_p$ and $K_c$ is given by the equation: $K_p = K_c(RT)^{\Delta n}$.For $K_p = K_c$,the value of $\Delta n$ must be $0$.$\Delta n$ is defined as the difference between the sum of the stoichiometric coefficients of gaseous products and gaseous reactants.For option $(C)$: $H_{2_{(g)}} + Cl_{2_{(g)}} \rightleftharpoons 2HCl_{(g)}$,$\Delta n = 2 - (1 + 1) = 0$.Therefore,for this reaction,$K_p = K_c$.
