Problem
When two elementary reactions are summed to obtain an overall balanced reaction at the same temperature and pressure, how is the equilibrium constant for the overall reaction related to the equilibrium constants of the elementary reactions?
(a) It equals the sum of the individual equilibrium constants, Koverall=K1+K2.},{
(b) It equals the product of the individual equilibrium constants, Koverall=K1K2.} ,
(c) It equals the geometric mean of the individual equilibrium constants, Koverall=K1K2.},{
(d) It equals the product of the reciprocals of the individual equilibrium constants, Koverall=(1/K1)(1/K2).} ]
