The following reaction, in CCl₄ solvent, has been studied at 25°C. 2BrCl ⇄ Br₂ + Cl₂
The equilibrium constant K_c is known to be 0.141. If the initial concentration of chlorine is 0.0300 M and of bromine monochloride is 0.0200 M, what is the equilibrium concentration of bromine?

Question

Quizplus · Accepted Answer

The equilibrium constant expression for the reaction is:K_c = [Br₂][Cl₂]/[BrCl]²Substituting the given values into the equilibrium constant expression, we get:0.141 = [Br₂][Cl₂]/[BrCl]²[Br₂] = 0.141[BrCl]²/[Cl₂][Br₂] = 0.141(0.0200 M)²/(0.0300 M)[Br₂] = 1.35 × 10⁻³ MTherefore, the equilibrium concentration of bromine is 1.35 × 10⁻³ M.
