The reaction N2(g) + 3H2(g) <----> 2NH3 Keq = 0.105 at (472 0c ) will be favored in forward direction or reverse direction ?

hey
Explanation: 

For this problem the concept that you need  to remember is that  the Keq sign tells us the direction of the reaction equilibrium.

If the Keq is greater than 1 the the reaction favors the forward direction but if the Keq is less then 1 a reaction favors the reverse direction .

For the reaction given above the Keq is 0.105 which is less then 1 which means that for this reaction reverse direction is favored

Answer: 

Since the Keq is less then 1 this reaction is favored in  the  reverse direction .
