The following question guides you through solving for equilibrium concentrations for a reaction using the FOIL method and the quadratic equation. The FOIL treatment and quadratic equation are given as a bonus question. For the reaction Bra(g) 2Br(g) at 1280 °C, the equilibrium constant is 0.0011. If the initial concentration of Br₂ is 0.063 M and Br is 0.012 M, calculate their concentrations at equilibrium. a) Write the equilibrium equation. b) Calculate Q for the reaction and determine the direction of equilibrium. c) Build an ICE table.…
