Assume th tos on either side of these equations are combined initially in equimolar amounts and that then the system is a reach equilibrium. Select the most appropriate description of each system at equ sure to distinguish elementary mechanisms from complex mechanisms in your discussions. equilibrium from the following list. Be A. At equilibrium, the products will be substantially favored (K 10') B. At equilibrium, the starting materials will be substantially favored (K 10). C.
