Unformatted text preview: 1 1. Which of the reaction sequences shown below yields the highest equilibrium c of final product C starting (in both sequences) with the same concentration of A? (Hint: Solve by mole fractions. Determine the mole fraction of C in both Sequences.) Sequence I Sequence II A " B Keq = 5 x 10-4 A " B Keq = 2 x 103 B" C Keq = 2 x 103 B " C Keq = 5 x 1Q- 4 L Sequence I Sequence II === B reaction sequences yield the same final concentration of product C. 2.
