Tutored Practice Problem 15.4.2 O Predict and calculate the effect of volume change on an equilibrium system Consider the equilibrium between COB, CO and Br? COBr() - CO) Brg) K -1.84 at 380K The reaction is allowed to reach equilibrium in a 8.20-L flask. At equilibrium, (COB) - 9.72x107MCO) -0.423 M and [Brgl -0.423 M. (a) The equilibrium mixture is transferred to a 16.4-L flask. In which direction will the reaction proceed to reach equilibrium? (6) Calculate the new equilibrium concentrations that result when the equilibrium mixture is transferred to a 16.4-L flask (COBr) - ICO) - Check & Submit Answer Show Apara

Answer 1

сох, а = cola - Bula Initial eam 9.72x10²M 0.423m 0.423M :ke=0.423) When volume is doubled, keeping other 9.72x102 variables constant, they incentrations become = 1.84 half of their original ones. Since, ca al :. New conclra 9.72x10² 6.493 0.423 = 4.86*102 0.212 0.212 Qc = 0.91 2x0.212 4.868102 Since, Qc a kc = 0.990 :. Reaction will move forward to attain equilibrium. coBoolg) - colg) + Bog'g) Ilm 4.868 102 0.212 0.212 C - n ta tu È (4.86x10²x) (0.212+2) (6. 212+). ke: 1.84 (0.212+2) 10.0486-x) 010447 & 2² +0.425n 0.0894 - 1.842 22 + 2.263x -0.0444 20 Solving the quadratic eqh, we get = 0.0196 in .
