8. 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 Bra 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.

8. 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.

Using the FOIL method carry out the multiplications an express the solution in the
form of a quadratic equation ax² + bx + c = 0. You may need to do this on a separate piece of paper and
then present your answer here. Show all work.
