The reaction H2 (g) + I2 (g) <-----> 2HI (g) Keq = 50 at 448 0C will be favored in the reverse direction or forward direction ?

Home >> Practice Problems

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 50 which is greater then 1 which means this reaction is favored in the forward direction



Since the equilibrium constant Keq is 50 which is greater then 1 this reaction is favored in  the forward direction.
