    Explanation:

    Step 1: Data given

    For the reaction aA + bB ⇆ cC + dD

    Kc = [C]^c * [D]^d / [A]^a [B]^b

    a. SbCl5 (g) ⇄ SbCl3 (g) + Cl2 (g)

    Kc = [Cl2]*[SbCl3] / [SbCl5]

    b. 2 BrNO (g) ⇄ 2NO (g) + Br2 (g)

    Kc = [Br2]*[NO]² / [BrNO]²

    c. CH4 (g) + 2 H2S (g) ⇄ CS2 (g) + 4 H2 (g)

    Kc = [H2]^41 * [CS2] / [H2S]²*[CH4]

    d. 2CO (g) + O2 (g) ⇄ 2CO2 (g)

    Kc = [CO2]² / [O2][CO]²
