The equilibrium constant for the reaction Br2(l) + Cl2(g) ⇌ 2BrCl(g)

1.	The equilibrium constant for the reaction Br2(l) + Cl2(g) ⇌ 2BrCl(g) at 27 oC is Kp=1 atm. In a closed container of volume 164 L initially 10 moles of Cl2 are present at 27 oC. What minimum moles of Br2(l) must be introduced into this container so that the above equilibrium is maintained at a total pressure of 2.25 atm. Vapour pressure of Br2(l) at 27 oC is 0.25 atm. Assume that volume occupied by liquid is neglegible. (Atomic mass of Br2(l)=80.
Answer» The equilibrium constant for the reaction $B r_{2} (l) + C l_{2} (g) ⇌ 2 B r C l (g)$ at $27^{o} C$ is $K_{p} = 1 a t m$ . In a closed container of volume 164 L initially 10 moles of $C l_{2}$ are present at $27^{o} C$ . What minimum moles of $B r_{2} (l)$ must be introduced into this container so that the above equilibrium is maintained at a total pressure of 2.25 atm. Vapour pressure of $B r_{2} (l)$ at $27^{o} C$ is 0.25 atm. Assume that volume occupied by liquid is neglegible. (Atomic mass of $B r_{2} (l) = 80$ .
