Consider the reacton of bromine and chlorine gas to form BrCl where Kp=1.11X10^-4 at 150K. A reaction mixture initially contains a bromine partial pressure of 755 torr and a chlorine partial pressure of 735torr at 150K. Calculate the equilibrium partial pressure of BrCl at 25^oC

Expert Solution

Br2 + Cl2 -----------> 2BrCl

I 755 735 0

C -x -x 2x

E 755-x 735-x 2x

kp = P²BrCl/P_Br2 P_Cl2

1.11*10^-4 = (2x)²/(755-x)(735-x)

1.11*10^-4 *(755-x)(735-x) = 4x²

x = 3.9

[BrCl] = 2x = 2*3.9 = 7.8torr
