In the synthesis of $HI$,the amounts of $H_{2(g)}$,$I_{2(g)}$,and $HI_{(g)}$ at equilibrium were found to be $0.8 \ mol$,$0.8 \ mol$,and $2.4 \ mol$ respectively in a $10 \ L$ vessel. Calculate the equilibrium constant $(K_c)$ for the reaction $H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$ and the equilibrium constant for the reverse reaction.

    $K_c = 9, K_c' = 0.11$
  • B
    $K_c = 0.11, K_c' = 9$
  • C
    $K_c = 9, K_c' = 0.09$
  • D
    $K_c = 0.09, K_c' = 9$
