PLEASE HELP :"( DUE NOW!!

What is the equation for the equilibrium constant for this equation?

CO+3H2⇌CH4+H2O

[H2O][H2]/[CH4][CO]

[CO][H2]3/[CH4][H2O]

[CH4][H2O]/[CO][H2]3

[CH]4[H2O]/[H2]3

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct

Explanation:

Step 1: Data given

For the equation aA + bB ⇆ cC + dD

The equilibrium constant is [C]^c * [D]^d / [A]^a*[B]^b

Step 2: Calculate the equilibrium constant Kc

CO+3H2⇌CH4+H2O

Kc = [H2O][CH4] / [CO][H2]³

The correct answer is  

[CH4][H2O]/[CO][H2]3

Option 3 is correct

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
