Philoid · Accepted Answer

Given equation:

Given, K_C =1 × 10^-4

By law of mass action the Equilibrium constant for the equation will be;

We know that the reaction quotient, Q_c, expresses the relative ratio of products to reactants at a given instant.

[Q_{c =} Reaction quotient]

Here; Q_C >K_C Reaction will proceed in reverse direction.

The value of Kc for the reaction 2HI (g) ⇋ H2 (g) + I2 (g) is 1 × 10-4At a given time, the composition of the reaction mixture is[HI] =2 × 10-5 mol, [H2] =1 × 10-5 mol and [I2] =1 × 10-5 mol. In which direction will the reaction proceed?
