The equilibrium constant for the reaction below, at a given temperature is 45.6. If the equilibrium concentrations of F2 and BrF3 are 1.24 x 10-1 M and 1.99 x 10-1 M respectively, calculate the equilibrium concentration of Br2. (4)

This is an incomplete question, here is a complete question.

The given chemical reaction is:

The equilibrium constant for the reaction below, at a given temperature is 45.6. If the equilibrium concentrations of F₂ and BrF₃ are 1.24 × 10⁻¹ M and 1.99 × 10⁻¹ M respectively, calculate the equilibrium concentration of Br₂.

Answer : The equilibrium concentration of Br₂ is, 0.0428 M

Explanation :  Given,

Concentration of at equilibrium =

Concentration of at equilibrium =

Equilibrium constant = 45.6

The given chemical reaction is:

The expression for equilibrium constant is:

Now put all the given values in this expression, we get:

Thus, the equilibrium concentration of Br₂ is, 0.0428 M
