Two reversible, elementary reactions proceed in the following sequence: a+b 2c 2 d +e the rate constants for the reactions are as follows, where ‘l' and '2' refer to the first and second reaction, respectively: k1,1=0.04 m-1.5-1 kır = 0.01 m-1.5-1 k2f = 0.10m-'.s-1 k2x = 0.10m-1.5-1 (a) if a solution initially contains 60 mmol/l of a, 40 mmol/l of b, and no c, d, or e, what will the distribution of species be at equilibrium? (hint: the equilibrium solution composition comprises five unknowns [the con- centrations of the five species), which can be determined by writing and solving five independent equations involving those unknowns. the avail- able equations include mass balances that characterize the stoichiometry of the reactions, and equilibrium constant expressions. try to write and solve five independent equations that characterize the system.)
