Close Problem Tutored Practice Problem 15.4.2 COUNTS TOWARDS GRADE Predict and calculate the effect of volume change on an equilibrium system. Consider the equilibrium between COBr2, CO and Br2. COBr2(g) PCO(g) + Brz(9) K = 0.254 at 350 K The reaction is allowed to reach equilibrium in a 8.60-L flask. At equilibrium, [COBr2] = 0.288 M, [CO] = 0.270 M and [Brz] = 0.270 M. (a) The equilibrium mixture is transferred to a 17.2-L flask. In which direction will the reaction proceed to reach equilibrium? to the right to the left (b) Calculate the new equilibrium concentrations that result when the equilibrium mixture is transferred to a 17.2-L flask.

Answer 1

Given, соса) Br₂cg) SO K = 0.254 at 350k [COBry] = 0.288M, [co] = 0.27 M T Bry] = 0.279 volieme .= 8.6.1 The equilibrium mixture is transferred to 17:2 L flask. ie: volume becomes double each concentration becomes half. I coor] 0.288 -0. luum. [.oe 0.27 0.135M [Br] = 0.135M bnew? to] [BG] 0.135X0.135 ECOBI o.luy 20.126 a new 4k 0.126 50.254 so products concentration decreases so in order to reach equilibrium again, the reaction will go to the right Now, new concentrations are T COBR] = [co] = TB2) olnym 0.135m 0.135M - Thank you!!
