What is the relation between the value of K_c for the forward reaction and value of K'_c for the reverse reaction in the reaction H_(2(g)) + I_(2(g)) hArr 2HI_((g))at equilibrium ?

What is the relation between the value of K_c for the forward reaction

1.	What is the relation between the value of K_c for the forward reaction and value of K'_c for the reverse reaction in the reaction H_(2(g)) + I_(2(g)) hArr 2HI_((g))at equilibrium ?
Answer» `K'_c=2K_c` `K_c=2K'_c` `Kc=K'_c` `K'_c=1/K_c` ANSWER :D
