Question

for the reaction h2(g)+i2(g)⇌2hi(g)predict the direction of reaction if h2(g) is added at equilibrium​

Answer 1

Answer:

reaction proceeds in forward direction

Explanation:

For the given equilibrium we can write

K=(hi)*2/(h2)(i2)

in the above written equation K denotes the equilibrium constant at a temperature.

here the equilibrium constant refers to the concentration equilibrium.

In the question it was given that h2 is added it meant that Concentration of h2 is increased (h2) is increased.

Equilibrium constant remains constant at a temperature.Unless we change the temperature the value remains constant .

From this to keep the K constant as it is done at a particular temperature .when we increase the concentration of h2 the K value increases so if we increase the numerator also to the same final value of concentration of h2.we can maintain the K constant. So, from this we can conclude that Concentration of hi is increased so we can say the reaction proceeds in forward direction.
