The reaction 2 a → b c has a kc of 0.2. the reaction is commenced with initial concentrations [a] = 0.2 m, [b] = 0.2 m and [c] =
LuckyWell [14K]
Kc = [b]*[c]/([a]^2) = (0.2 M)^2/(0.2 M)^2 = 1.0
To achieve equilibrium, Kc must be equal to 0.2, therefore Kc must decrease, so the concentrations of b and c must decrease and the concentration of a must increase, meaning the reaction will proceed toward the formation of a.
