Unformatted text preview: where K = 1 . 23 × 10 2 . Initial concentrations of A and B are each 1.00 M. Determine the concentration of reactants and products at equilibrium . We setup our ICE chart A B C I 1 . 00 1 . 00 C − x − 2 x x E 1 . 00 − x 1 . 00 − 2 x x We now use the equilibrium constant, K = 1 . 23 × 10 2 = x (1 . 00 − x ) (1 . 00 − 2 x ) 2 (8.2) We can rearrange this to give 492 x 3 − 984 x 2 + 616 x − 123 = 0 (8.3) Unfortunately we are now faced with a cubic equation to solve.
